you dont need to watch this movie. just watch trailer

Unfortunately the OP has a point. The trailer on here basically gives away every single plot point of the movie, from the very beginning to the very end. Don't watch it if you've never seen the movie and are interested in seeing it.

I remember the promo ads on TV when this movie first came out (I was about 13), and they gave away almost nothing of the plot - they showed just enough to make it look intriguing and make you want to go see it. The trailer on the IMDb page is like most movie trailers these days - the entire story is crammed into it, so when you do go see the actual movie you feel like you've already seen it. It sucks. I try to avoid watching trailers in theaters whenever possible.
