Continuity mistake: At the skate park (which is supposed to be Thursday after school), Max is wearing the clothes he wore on Wednesday and Friday - not the clothes he wore in school on Thursday.
Continuity mistake: The contents of Hannah's purse that Thor dumped out on the table is inconsistent. While acknowledging that Thor did mix them up once and the position of items were rearranged, this cannot explain how no money ($20 bills) was on the table after Thor slid one bill off the table or how the money is back on the table several seconds later. Some money near the center of the table also suddenly appeared under Max's hand. (00:23:01)
Continuity mistake: In the opening scene, the pillow propped up against the rear bed frame and parallel to the back of the erected laptop screen changes position a few times. The distance between the pillow and the open laptop varies from initially about one foot down to a couple inches (or almost touching). Depending on the camera's position, the pillow should have been obstructing the view of the laptop but did not because the pillow was (magically) shifted about 45°. (00:01:16 - 00:01:49)
Revealing mistake: The 3-light tree floor lamp in Soren's house (upstairs where Lucas and Thor encountered Hannah and Lily) has "fake" lights. Instead of seeing light from actual bulbs, each is simply a solid white circular shape. (01:16:30)
Continuity mistake: The way Max wrapped around and tied the cord to a decorative (inner) bed post is different immediately after he turns around to get back on his bed. The double loop, knot, and last few inches of the cord are instantly a single line that looks squarely clamped at the decorative post. A second later, it is tied differently again with the end of the cord in back of the larger end post. (00:01:46)
Continuity mistake: During the back-and-forth shots of the Good Boys facing the school and the girls (Hannah and Lily), the long-haired woman (wearing a white blazer/jacket and skinny jeans) walking briskly from the left side of the screen toward the right side is not properly coordinated with the shots. At times, she is not as far along as would be expected. She also walks from behind Lucas' back to off-screen (right side) two times. (00:27:30)
Character mistake: At the skate park, Thor said he wasn't into girls because "girls are a distraction." Thor was interested in going to Soren's party because a lot of the popular boys were going to be there. When the "spin the bottle" landed on Thor, he said he couldn't kiss Brixlee and went upstairs. Hannah and Lily came home and told Thor it was OK that he wasn't ready for a kissing party and still had a lot of time before becoming interested in girls. Max previously told Thor that he wasn't as mature (sexually developed or undergoing puberty). Therefore, Thor's statement in the cafeteria about his new earring - that he "wasn't going for cute", he was going for "sexy and hot" - was incongruent and incompatible with his character.
Revealing mistake: In music class, the position of Max behind Lucas would not enable Max to see Lucas' face to know he was crying or ask "what's wrong?" In this part of the scene, Max appears to be green-screened and his eyes are focused too far left of the back of Lucas' head (not just face); he would be lucky to be able to see a part of Lucas' left ear. (00:09:58 - 00:10:32)
Revealing mistake: Benji was talking to Hannah in the back yard near the swimming pool and many feet away from Hannah's house. Eventually, a large white beam or horizontal area appears behind Benji's head. Although this doesn't make sense, it apparently is meant to be the overhang of the house. Benji was too far away from the house to be "under the overhang" plus the overhang is not nearly that wide. (00:19:40)
Continuity mistake: When the boys go into the woods to "sip a beer", the background changes several times. Most noticeably, there is a graffiti-painted wall or boulder that is clear, colorful, and directly behind ALL the boys on at least two shots. In other shots, the wall is completely missing, only partially visible, or very pale and at an angle.
Continuity mistake: At the skate park when the camera is on Max, Thor, and Lucas (in that order, on their bikes), the background changes a few times. The houses (which might change) and cars passing on the road show that the road is closer or further away and/or at an angle. People behind Max disappear but reappear in the same spot with camera changes in direction. When Max rides his bike a little ways to talk to Taylor, the pavement changes in color (painted areas).
Continuity mistake: The amount of orange soda/pop in Lucas' glass decreases and increases at least twice even though he didn't drink or add any. (00:09:13 - 00:09:42)
Continuity mistake: At the store, when the background looks pale and at a slant (indicating the use of a green screen), the man behind the counter makes the same head and eye motions on two occasions (obviously taped) and his eyes don't appear to be looking at the "live action" - he appears to be somewhere else (like on a pre-recorded tape).
Continuity mistake: After the drone gets smashed by the school bus and the Good Boys run across to be facing the school, the background changes a few times. For example, students who are standing together behind Max suddenly disappear, but are back in the same spot when the camera changes direction again.
Continuity mistake: At "Galleria Tech", a male employee in a blue shirt approaches from behind the Good Boys. A little later, he is picked up again, but at an earlier starting point.
Continuity mistake: At the "Rock of Ages" show, Thor has a lot of "powdered sugar" between his upper lip and nose (like a thick mustache) when he comes out the door and falls to the floor but there is no sign of any "powder" when he raises his head. (01:19:22)
Continuity mistake: The position of Max's legs/feet change a few times when he is lying on his bed, varying with his dad entering his bedroom and leaving. Max's feet are in the air (perpendicular to the bed) right before his dad comes in but are crossed and flat against the pillow when he enters. When Max's dad rises from sitting on the bed, Max's feet are in the air again but are down on the pillow again when his dad is at the door leaving.
Continuity mistake: Throughout the time the Good Boys are in the school's bathroom, Max's collar is sometimes partly under his jacket / backpack strap and other times it is not. (00:30:37)
Revealing mistake: A stunt double was used for Lucas flying off his bike and into the side of a delivery truck. The legs are obviously thinner; Lucas isn't that "thin." Even though movie goers could assume that a stunt double would be used in this situation, the director / producers apparently did not even try to make the stunt double pass as Lucas - and all they needed to do was make the stunt double wear bigger pants (Lucas' size) and add padding. (00:36:58)
Revealing mistake: The use of a green screen (or other color) during most of the cafeteria scene is obvious if you watch the people in the background instead of the main characters and is flawed in a few ways (e.g, varying angles, greater distance, continuity of a person, etc). For example there is a man wearing a blue shirt/tan pants and carrying a briefcase walking down the aisle toward the Good Boys' table. When the man is walking along the wall that is behind the Good Boys, he is further ahead than he is when he is picked up again. Also, this man shows up in front of Max when Max is walking to Soren's table. The man also appears walking along the back wall with a woman. Watching the wall behind Thor and Lucas, it is sometimes at an angle and other times looks more distant. Some of the people would essentially be walking "out of the wall" in order to appear where they do (e.g, the boy with a backpack).
Answer: Max's dad probably over-reacted out of anger/rage over the drone and destroyed room and might have made changes after he cooled off. Plus, it was meant to be humorous. A "month in the hole" was immediately imposed; no more birthdays, holidays, summer, etc. would refer to after the month in the hole. Max's dad did not say he couldn't attend school-related events, such as the "Rock of Ages" show. Parents are supposed to give their kids unconditional love. A father can continue to love his son while disliking his behavior. Max's dad may have been unduly harsh (again, out of anger), but he still loves Max - which shouldn't be depressing. I don't think Max's dad said he was grounded for life, just grounded. However, Lucas told his parents that Max was grounded for life - an exaggeration.

So, even after being grounded for a month, he can't celebrate his birthday or summer vacation?
Not necessarily. Max's dad said those things in the heat of the moment. Although it is possible that Max's dad meant what he said (at least at the time), it isn't probable. The severity of the punishment given to Max was a reflection of how angry Mr. Newman was. A proud and loving father who tells his son "I will always love you..." is more likely to forgive Max so that they can return to their good father/son relationship.
