An old show by today's standards, but just finished it and it was great! Check it out on Netflix, if you haven't already.
I am rating this a 10/10, just to help make up for some lower rankings left by others. It's really between 8.5 and 9.5. It's hard to rate a series off of 13 episodes. It's a shame this show didn't get renewed for a 2nd season. I think 26 episodes would have been sufficient in telling a better story.
It has action, drama and dinosaurs. Very futuristic, yet takes place in a prehistoric wilderness, which makes it unique. The characters are good, mainly centering around the lead character's family and Commander Taylor, who is in charge of Terra Nova. The personalities and dramas that stem from these characters aren't wildly ambitious but do a good job with mixing in the environment and creating conflict with all the dangerous elements: dinosaurs, diseases, and the Sixers (human antagonists).
I read a review on here complaining about all the plot holes. One major plot hole complaint was "why aren't the future people putting on sunscreen when they get here?" Seriously? That's your big plot hole. First of all: maybe they are and it's just such a boring addition that it's not even necessary. That would be a waste of time. Who wants to watch that? Secondly, it may be an oversight but so what? It's science fiction. Suspend your disbelief a little bit. Obviously cracks in time don't really exist, but if they did........well, that is the basis of the show. If you can't get over that and start nitpicking about sunscreen right off the bat, then maybe this show isn't for you and you should watch people crossing the street outside your window. Can't get any more real than that!
Last little fun fact: the pink ranger from the new Power Rangers is in this. Also, the new inhuman director of S.H.I.E.L.D. from Marvels Agents of SHIELD.
