The two hour premier did a pretty good job of introducing the characters. The initial scene set up the world and got the viewer emotionally invested. We understand what kind of family this is and what they will do for each other. Special effects are at a tv level. They did an overall good job on the dinosaurs, but apparently they didn't get the news that dinosaurs have feathers.
Overall it was pretty good show with enough story revealed that I will be tuning back in. I think they showed too much of their hand at the very end, though. I was completely willing to go along with not knowing about that for a couple of episodes. Or maybe just a partial explanation, but they revealed the whole thing.
My problems would be with basic things in the story. A wife that works in public hospitals has the ability to collect a rucksack full of money. A future high security prison that someone is able to sneak/bribe her way into and pass off a laser that allows escape. A rucksack full of money lying pretty much in the open. Being able to bribe your way onto a launch window. Those are just a couple of the things.
The show wasn't perfect, but it was pretty good. I was willing to overlook or ignore most of the little problems though and that is a pretty good sign. Apparently, only attractive people get to travel to Terra Nova so that is a plus. It is worth a watch though. Glad I gave it a shot.
