Everyone hates when certain thing happen in movies they watch, no exceptions. Here my personal examples:
- Anti-climatic and/or no resolution endings (Gamer)
- Sex scenes that come out of nowhere. Its really awkward (all of Uwe Boll movies)
- Editing magic in fantasy settings that is used when convenient to the plot and needs no explanation (Thor)
- Forced romance where the couple have no discernible reason to be together (Twlight)
- Really long and dragged OUT endings (Transformers series)
So what really pisses you off when you see in movies even if its a movie you like.
