Which is a truly horrifying thought, considering what a botch that plotline was (and ruined a premise that had great potential).
I still maintain time travel is the most difficult sci fi concept to do well. It torpedoed ENT, and it's the single most damaging element in Heroes (granted, there's a lot of competition for that).
Look at the movies and shows that do time travel well - Twelve Monkeys, Lost. What they have in common is discipline and restraint. The writers decide what the rules of time travel are, communicate those rules clearly and unequivocally to the audience, and stick to them. But time travel opens up so many possibilities that writers can be distracted and sloppy, leading to plotlines that are silly, excessively illogical (illogic is inevitable so the goal is just to reduce it as much as possible), and retreads of stuff we've seen before.
The time travel stuff will probably just be reset-button-of-the-week. So I'm not counting on the writing to carry the show. They should hire some actor who can draw an audience - Ben Browder, Adrian Pasdar, Lee Pace. There's three entirely different actor types, depending on how they want to spin it. (Heck, all three could play distinct characters in the same series, how awesome would that be?
)
