I have a few problems with movie trailers: 4. They are just clips of the movie spliced with big letters when they could be like video game trailers(original footage with original music just for the trailer)

The problem with this is that it would likely allow them to misrepresent the movie even further, because now you aren't seeing any part of the movie at all just something inspired by it and for all you know the inspired by it footage is superior to the movie in every way because it is meant to sell the movie. At least when I see clips of the movie I get a feel for it based on the movie itself, and while sometimes the trailer will make the movie seem better than it really is, at least you aren't looking at something that has nothing to do with the movie at all and going in blind praying it will be good. I agree with you though I really hate when I see a funny movie trailer, and get the movie home and find that those scenes were the only good things in the entire movie. I usually wait until I have some reviews from friends or family before I watch movies these days because of that.

My main thing that pisses me off about movies themselves though is when they adapt a book to the screen and they change a ton of parts in the book to the point that I can't help but think "Where's x?" or "Why didn't they show y?" I had this happen last night when I was watching Goblet of Fire since I somehow managed not to watch it before I got it for Christmas. They cut out 90% of the first quarter of the book and since they cut Winky out they changed where the character's seats were in the stadium at the beginning then didn't even bother to show the damn match. Maybe it is just nitpicky but stuff like that annoys me. I get that it is hard to adapt 500+ pages into a 2-3 hour film, but sometimes it is hard to swallow some of the changes they make especially when it is a book I enjoyed. At least they tried though, some movies don't even try to follow the book. Sahara for example is nothing like the book it is "based on" at all with the exception of the character names, the plot is completely different. My brother always gets pissed when we watch a "book movie" because at the end I'm always saying "Well they changed this and that, and the book was so much better."
