read something that said ideally 7 years, minimum 3 to tell the main story arc in a believable manner.
As for comparisons with Lost, it's more Cinematography, lots of lens flares, some of the special effects, Plus the focus on an Oceanic Air sign in the opener. Considering it's more or less supposed to be ABC's replacement for Lost, making it seem reminiscient of Lost, should help bring in viewers.
Well, I could make some additional comparisons.
The opening in general reminded me a lot of LOST. Guy wakes up after a terrible accident and the world around him has gone to hell. He tries to help.
Also, there's the flash forward itself. I know LOST didn't invent flashbacks or flashforwards, but they seemed to have reinvented it, or at least taken it to a new level. So that feels very LOST to me as well.
That it seems to be a potentially sprawling ensemble we're attached to, who are all somehow connected, instead of just the Jack Bauer hour. (I know 24's more ensemble than Kiefer, but still...)
Still, I'm a HUGE LOST fan (in case I haven't made that clear) and I really enjoyed this first episode. The acting was great, so was the intrigue, and the hooks came right where they needed to. Oh no! The kid's dad is going to be Olivia's lover! Who's the mystery man walking around in the stadium?
The daughter giving Joseph Fiennes the friendship bracelet scared the hell out of me and made me a bit heartsick. Considering how both his marriage to Olivia (Hello, Penny!) breaks down, well, I'm very worried. And of course, I'm worried about John Cho. I half expected him not to make it out of this episode (that would've been terrible)! So, all in all, I'm invested and very curious to see where they go.
Although I'd hope it's shorter rather than longer. 6 months doesn't feel like seven seasons to me. Although they could probably spend a whole season post-flash forward.
