DVR's set, but this is one show I could easily delete without watching. There were too many ginormous plot holes in the first two seasons for me to take the show seriously. If all those "transgressions" aren't immediately explained, or compensated for, in the opener, then my interest will flag right off. As it is, the show's just fancy background noise.
The basic problem is that there is no excuse for any of the heroes to be alive. There needs to be a damn good reason for that; enough milking already.
