I'm not sure I'm ready to commit to a humorless series in which 9/10ths of the characters have already shown us the bleak future they're headed towards in the next 6 months.
I was also very not impressed by the seeming "check off the boxes" that seemed to fill the episode.
Roguish, drinking law-enforcement guy with a marriage on the rocks? check
Idyllic morning scene to establish the characters, complete with them rising for the day in a massive suburban LA home? check
Doomed sidekick? check (only, we already know that ain't gonna happen)
Creepy kids? check
Overblown disaster scene trying to top pilot of Lost (I expect this will be a new prime-time series standard)? check
There's the mystery of "what happened" which can't be much of a mystery for long as there's a novel out there upon which the series is based. That said: I presume the "why" will be changed, just as the protagonist is no longer a physicist, but an FBI agent.
Anyway, the show did have a good hook (everyone passed out for 2 minutes!), with a sort of awkwardly revealed twist (and saw their future. sort of!). But the producers saw to it that the characters started off as generic TV characters, and not particularly interesting ones at that. So knowing where they're headed doesn't actually add a whole lot of appeal.
And, while I'm sticking with ABC's Lost to the bitter end, Jason said it best when he rolled his eyes and began to complain about how common time-travel/ glimpses of the future/ etc... have become in TV these days. Which is interesting, considering what a pain time-travel is in any medium or genre, and how badly its usually executed.
I might also mention (and I'm a little ashamed I know this), but Smallville is basically doing the same thing this season by giving Lois a flashback/ flashforward for the season.
