Excellent ideas and effects though, wowwee. Elevator between UK and Australia is visually brilliant and interesting. No one on set grasped more than a 4th grade level of geology and physics, but hey, it's still fun.
Colin Farrell, hang a WTF sign around his neck, and you could trim 75% of his camera time. Jessica Biel is underutilized. As is Bryan Cranston.
And oh the lovely Kate Beckinsale. She's the difference between 2 star and 3 star, though I'm not sure in which direction. Let's see, cop, ex-wife, corrupt, gorgeous, ruthless, slavish to the main villain, salon hair. Pick two, or four at the outside, but never saddle her with all seven. Dude that's just rude.
