#1 is better than #2, but both make your heart stop.

I think 2 was better than 1 for the first 16 hours, but the post-[spoiler removed] stuff was so over-the-top unrealistic (particularly post-9/11) that it was really distracting....

The timing of 2 was all screwed up. It should have ended at hour 16 or shortlly thereafter. 1 was great beginning to end.
