After actually watching the trailer I've been put off badly by this movie. Not to mention some of my friends being dragged into it and hating it.
I believe if you enjoy seeing everything getting blown up, no character development... in fact no main characters AT ALL then you'll love this (quite a few action junkies do apparently) but that's not for me.
Apparently the plot line is -
One person dies... second person dies... a bunch of people die... everyone dies.. the end.

Save yourself until next week and go watch Cloverfield.
