Watched it today, fun movie.
I didn't really expect anything and was trapped on a plane for several hours so i couldn't escape.
Was like a mixture of S.W.A.T. and Independence Day with some Black Hawk Down elements thrown in. Michelle Rodriguez plays a hardcore Marine/solider girl that could kick a man's ass and kills some aliens, need i say more about originality?
If you're older than 10, you have seen it all before somewhere, but if you have enough beer and some finger food, it's k to watch.
On a side note, "Sucker Punch" was much better.
