Oh, quit laying an egg about it. "Mind Boggling!" "doom"! Waah waah.
You watch the movie after you know what's going to happen and you think that's not retarded?
1. Considering most movies are based from pre-existing material, it's not a huge leap.
2. Nor is it a huge leap from reading a review or having a friend tell you about it.
3. Most movies are predictable enough anyway. I didn't have to read spoilers on Iron Man to know the old guy was gonna betray him. (And I didn't, BTW.)
4. Media outlets and boners like you can easily be found spoiling the movie without any work on my part. You go spoil a book people waited for years to read, and then whine that I spoil myself on movies? WTF? Seriously?
5. I am easily spoiled. One sentence hints actually spoiled "The Sixth Sense" and "The Happening" for me. ONE SENTENCE
HINTS. Not even direct spoilage.
I don't watch many movies these days. I have to pick the ones I get to see carefully. Unless it's an actor I really like or the preview or premise looks rad, I can't be bothered. I don't have the time or money or internet connection for ten crappy movies just to see one decent one.
Just because something sounds like shit in a spoiler doesn't mean that when its presented in the medium that ya know...
In my experience, yeah, it usually does. In addition, stuff that sounds cool usually looks cool.
