Peeves in movies:
Japanese horror movie American remakes. Seems like Japanese horror comes in two brands - Godzilla and ghosts. Nothing wrong with either, but culturally their stories just don't translate. And leave it up to American filmmakers to pretend that these remakes are something that they're not.
Blair Witch movie techniques. It wasn't effective in the original, it isn't effective in the reuses. The only thing that goes through one's mind when watching is how contrived the amateur filmmaking looks and how much more entertaining it would have been shot as a "real" movie.
Movies that go out of their way to emphasize how disfunctional and depressing family dynamics can be. A prime example is "Brothers Three", but there are countless others. I suppose it's a way to try and make what is otherwise ordinary filmmaking of ordinary people "interesting".
Movies that show children as heroes, saving either the world or family relationships. Inevitably, parents and/or grown-ups of all ilks are shown as dolts, slow-witted, with anger as their only emotion. Children are NOT intellectual, intuitional, emotionally stable, and far-sighted individuals. They are selfish, controlling, impulsive entities that need adults to learn how to be human. That goes double for teen-agers.
Any movie which aims at an intelligence level of a ten-year-old boy, but uses emotionally-stunted adults (almost always male). And then to call them comedies. Those emphasizing potty humor, dumber than dumber humor, American Pie humor, etc.
