I did it myself (
Jurassic Park/
Lost) but one thing people could keep in mind is that
Jurassic Park and
Avatar (which I don't see as that was about sentient aliens) are films that have come and gone and
Lost (and apparently
Outcasts) are TV shows that are over and done with. From the restricted perspective of American network television, there's nothing remotely like it on now. We have a truckload of crappy cop shows and a handful of ghost/witch/fairy tale stories.
A Person of Interest strikes me as a typical CBS cop show with a magical computer program and
Fringe is basically occult weirdness like the
X-Files was (comparing by type; not derivative-ness). What
Terra Nova basically is, is an SF story (yes, in the TV nonsense style, but in its own terms it is) of colonizing what is essentially an alien world with alien critters, despite it being "our" world with "our" dinosaurs. (And, depending on the timeline interpretation, maybe it isn't even our world.) IOW, it's one of the purer SF themes around. I find the "Dinos ate my baby!" (or are trying to) theme of both the first eps to be tiresome already and, as I said, I dread the bottomless conspiracy they may bring on, but I'm still fully tuned in for our colonizing story and I hope SF fans everywhere do so.
Is it great? No. Is it passable. Definitely, so far. Is it SF? For TV, certainly. Is there anything else like it on
now? Nope. Do we want to see more SF? Yep. So let's watch it and encourage this sort of thing. If we were to ever get more options, then we could get pickier. As is, the networks keep bringing on one SF show at a time (after phases with nothing at all) and then everyone attacks it and it gets cancelled before the season's out.
[1] It'll never get better that way. We need to have a hit SF show so the other networks can go into clone mode, saying, "We need our own SF show!"
-- One thing that makes me vaguely optimistic is that final US Nielsen rating for both episodes look to be 3.1 (even with FOX's idiotic idea of scheduling it opposite
Monday Night Football). That's fine in the abstract, but not enough for a show reputed to be this expensive. But it is 100% retention, which is remarkable. If it could actually trend upward (which it could do by just putting it on Tuesday or something!) that would be great. All (or almost all) other shows this season have lost something on the order of 4% to 33% of their audience each week.
[1] V, ludicrous and miserable as it was, lasted two half seasons which equals one and doesn't really refute the point.
