CGI specaial effects.
Retarded humor: quirky gags, over-the-top reactions, frequent puns.
Retarded adults & genius kids (My one exception is A Series of Unfortunate Events...the books anyway, becauwse it's explained why).
3D animation.
Talking animals.
Robots that have feelings. (Wall-E, Transformers, Iron Giant).
Remakes & sequals.
Sex scenes: In normal movies, they're short, pointless, & boring. That's why we have porn.
Over the top unrealistic special effects in action movies.
Macho antihero antagonists who are as smart as they are strong.
Dumb henchmen who can't shoot straight, slowly creep up when they could be shooting, & just stand there waiting to get taken down by one guy.
Complete lack of originality in horror movies.
Hyper-emoional weak scardy useless dumbshit women as love interests.
Completely unfaithful to the source, be it game, comic, or novel.
Adults who overact in children's movies.
Action movie badasses from decades past in children's movies (Jackie Chan, the Rock, Arnold).
Comedians who were funny about 20 years ago, but are now just annoying. (Jim Carrey, Robin Williams, Brendan Fraser, Adam Sandler).
