Wishbone: I'm reminded of
Terra Nova, which explores the same concept, only it is set 85 million years ago rather than just 10,000.
chezybezy: awh someone beat me to it - they really really need to pick up the second series of that show!
That was the first thing that popped into my head as well.
I think the show is pretty definitively dead though, I seem to remember reading only one other company was interested and even they decided not to continue it in the end.
Which is too bad, it wasn't a great show but I liked the premise and I think it could've matured into something nice.
The opposite of Lost which I felt kept getting worse and yet didn't get canceled.
