Here's my top 5 list of fictional tv/movie/video game events that just drive me nutty:

1. Seeing a woman take on a guy twice her size, and win.
2. Sex scenes. They're just inappropriate and unnecessary.
3. Watching as the hero of the story falls into an obvious trap... And then somehow survives unscathed.
4. Seeing the hero of the story lose his weapon... Again.
5. Seeing a puny hero take on a massive enemy... And beat the living snot out of it, because of some random blessing or whatever.

Please no off-topic discussion of another's list... I want to encourage honesty here
