BSG(2004) *was* awesome, in the beginning. Unfortunately they managed to completely screw it up and jump the shark by season 3. That whole "final 5" thing was idiotic. Like "Lost", it became clear they were just making shit up as they went along, instead of having an actual plan, and a good reason why the Cylons had it out for the humans, so the longer they drew it out, the more convoluted and ridiculous it had to become.
Extant wasn't *that* bad, and did have a lot of potential. I liked how it showed self-driving cars. The part about it being centered around an interracial couple where the *woman* was black was a refreshing change too. It was also nice that this couple consisted of a smoking-hot woman, and a not-so-hot, rather nerdy guy who's an engineer. Totally and completely unrealistic in American society of course, but it was nice to see. Engineers are never the stars and never get the hot women in American TV, and this show bucked that trend (as did the Iron Man movies to an extent).
Lost was not great. Well it was at first (like BSG), but jumped the shark, because just like BSG they were just making it up as they went along. It just got too tiring to watch so I gave up after 5 or 6 seasons I think. At least BSG had the good sense to have a real ending after 5 seasons instead of drawing it out for a decade.
Terra Nova was an utterly fantastic idea, and while obviously very family-oriented (it was on Fox after all), was entertaining to watch. But the bit about the angry son was somewhat lame. I still dream of making my own wormhole and moving to the Jurassic period.
These retards keep cancelling the good shows after 1 season. How the fuck do you expect to build an audience if you keep canceling the dam things??
The problem is that airheads who watch Honey Boo Boo don't care for quality sci-fi shows, and the people who do don't subscribe to cable and don't watch commercials. Netflix may change all of that, hopefully.
