Deliberate mistake: When Johnny is watching the news footage of the Hulk battling Thing, all the footage is merely clips from that portion of the episode, including parts of the battle that were happening before the camera crews even showed up. (00:02:50 - 00:07:20)
Revealing mistake: When Silver Surfer is flying between the buildings with the Statue of Liberty in the background, the building on the right briefly vanishes from the screen. (00:00:55)
Behold, a Distant Star - S2-E10
Character mistake: When Sue is brought out of surgery, her father can be seen wearing a watch. Surgeons don't wear watches or any other kind of jewelry when performing surgery, as they can't be sterilized and can also get in the way of gloves. (00:05:00)
Behold, a Distant Star - S2-E10
Continuity mistake: When Franklin Storm is telling his children not to cry, Sue is stroking his hair with her right hand. When the shot changes, her right hand is resting in front of her right leg. (00:14:08)
Behold, a Distant Star - S2-E10
Continuity mistake: When Sue is talking about her father going into hiding, the camera is on the right side of a photo album, showing a newspaper clipping of him being wanted for murder. When the shot changes, the contents of that page are now three different photographs. (00:07:32)
Behold, a Distant Star - S2-E10
Revealing mistake: When the heroes are in the Fantasticar looking for the Skrulls, they fly by the same group of three buildings seven times, and from two opposing camera angles. (00:15:02)
Revealing mistake: When Nova blasts through the building, the wall where the hole is created has already been drawn as misshapen and discolored, likely to make it easier for the animators to animate. (00:02:53)
To Battle the Living Planet - S2-E6
Factual error: The Moon is around 238,000 miles from Earth, but when the Fantastic Four go out into space to find Thor, the Moon is extremely close to Earth. (00:04:11)
The Silver Surfer & the Coming of Galactus: Part 1 - S1-E5
Continuity mistake: When Reed is stretching up to speak to Galactus, the black 4 on his chest briefly turns white. (00:20:04)
The Origin of the Fantastic Four: Part 1 - S1-E1
Other mistake: When Puppet Master is making a clay figurine of Thing, the mold he uses doesn't have a Thing-shaped interior with which to make a detailed figurine. The figurine should have just looked like an undefined human-shaped figure. (00:15:20)
Other mistake: When Dr. Doom glides into Silver Surfer's cell, Surfer is resting on his hands and knees, and the surfboard somehow gets under his hands and left knee without lifting them off the ground. (00:15:15)
Continuity mistake: When Silver Surfer is sitting next to the lion, his right hand is resting on the ground to his right, and his left hand is resting on the lion's back. When the shot changes, his right hand is suddenly close to the lion's face, and his left hand is no longer touching the lion. (00:00:13)
Continuity mistake: When Reed, Sue and Thing depart to battle Dr. Doom, Thing is wearing a sleeveless shirt and tights. When they all jump out of their plane, Thing is shirtless and wearing trunks when he begins sliding down the tree, and then wearing the shirt and tights again when the camera returns to him. (00:17:13)
Continuity mistake: When Reed is apologizing to Thing for using him as a guinea pig, he is standing next to a two seat sofa, which is in front of window. When Thing takes a swing at Reed, he is now standing next to a single seat chair with no window behind it. (00:13:35)
Continuity mistake: When Black Bolt opens the doors to the room with the oxygen meter, the white stripes on his uniform are incorrectly colored blue. (00:04:16)
Continuity mistake: When Reed puts his suit on to help Thing battle Sentry, his gloves only go up to his wrist. When the shot changes, the gloves now go midway up his forearm. (00:16:37)
Behold, a Distant Star - S2-E10
Continuity mistake: When the doctor first walks into Sue's hospital room, there is a vase of flowers and an unidentifiable object at the foot of her bed. As the scene progresses, the two objects become further apart from each other. (00:03:38 - 00:04:14)
Answer: Gleaned from the Internet: Much of the negative reaction was due to the poor, simplistic, and outdated quality of the animation where the characters moved stiffly and clumsily through scenes. There were also some obvious animation compositing gaffs. The animation colors were also criticized as being overly bright and cheery and out of character to the established story's darker tone. The broad humor of the first season was replaced by a more mature narrative between the characters.
