It didn't suck. I was pleasantly surprised and rather enjoyed myself.
Jake Gyllenhaal was fantastic, if you get past the fact that he's a white guy. That said he had a decent script, acted well and ran around without a shirt looking hot. very hot. I enjoyed the story a lot and it had enough of a twist to keep me happy at the end. (though I was hoping for a little more 'rocks fall; everyone dies'. call me perverse)

In the end only 2 things bugged me. 1) The afore mentioned lack of a brown lead, or any non-whites in speaking roles. 2) Is that it utterly FAILED all points on the Bechdel Test. (To the extreme point that they bloody KISSED during a CHASE scene. really? seriously gag me please)

But for a fun friday with your SO I recommend it.
