I don't even like watching trailers because I can predict the fucking movie when watching it by going "oh that clip hasn't been shown. This is that part. Oh hey it's that funny scene that is now no longer funny since I saw it coming thanks to the trailer." Now what would've been funny clips, is now ruined for me. So, again, thanks dick.
And I know I'm being a picky bitch about spoilers, but come on, man! I've been waiting for this movie since Iron Man 1!
