Overall, I liked the the whole "Terra Nova" 2 part pilot episode "Genesis". The show has a lot of potential, with the introduction of a few mysteries and nasty dino's. As for a pilot episode, it did what it needed to do, mainly grab my attention and leave me wanting to see and learn more about the show, and hope that it will smooth off the rough edges.
My biggest problem with the show are the IDIOTIC TEENAGERS! I can only hope that the same amount of time devoted to the teenagers in the pilot is not the same in all the rest of the episodes. If they do continue with a lot of the teens, I predict the show will not make it past one season, maybe even getting canceled during the first.
