I happened on a reference to an interesting sounding TV series that only lasted one season but was very well done setting-wise,
Terra Nova. It seems to have been filmed in Australia back in 2001-2 and was about the world in 2149. The planet had developed a toxic atmosphere, no survival outside without breathing apparatus, overpopulation, etc. A rift in time is found allowing limited numbers of people to travel 85 million years in the past and set up a military colony. The series follows one family of colonizers and the efforts of the colony to survive against dinosaurs, an attack from 2149, and a rebel element also surviving in the past.
Spielberg was one of the producers and the scenery of Oz and the CGI was outstanding. The scripts/plots were way too familiar, and simplistically written. The actors were very good I thought. I could only find it on Amazon (new in sealed jewel case) but it was worth it. According to IMDB it was canceled because of escalating costs and Oz's foul weather. A shame, as with better writers it could have been a bigger hit than it was.
It's listed as a Canadian edition DVD English & French.
Edit: I don't know how I missed this back in 2002...I'm a Sci-Fi buff; this would have thrilled me - A Sci-Fi series on TV. I can't imagine what else I would have been watching. Maybe I mistook it for some boring science series...
