Corrected entry: When Max is revealed as the head vampire, Star makes the realization that "YOU'RE the secret David was protecting" but there is no previous reference anywhere in the movie to a secret that David is protecting.
Corrected entry: At the end of the movie when the vampires come back to get revenge they never asked for permission to enter the home the way Max did. All vampires must get permission from the head of the house to enter.
Corrected entry: Max makes a point of being invited in, and at the end mentions that inviting a vampire in makes you powerless to them. But who invited David, Carlo and the others in?
Corrected entry: When everyone is eating dinner with Max, Sam says "would you like some Parmesan cheese?" Max then puts some on his spaghetti and says "it's not cheese, its garlic." Sam's mom takes the bowl and smells it to check. Considering it's minced garlic, everyone at the table would've smelled it! I realize Max and the boys knew it was garlic but the mother did not know this and wouldn't have had to put it right under her nose to smell it.
Corrected entry: During the grand finale when the vampires are in Sam's house, he shoots Dwayne with a bow and arrow and Dwayne falls to the floor pretending to be dead. His left arm is down his side. The shot changes to Sam who is looking at him and then returns to Dwayne whose left arm is now up next to his head so that he can push himself off the floor. (01:22:15)
