Player Affinity writes: ""Nightfall" perfectly illustrates why Terra Nova's choice to be all things to everybody — by attempting to deliver a fast-paced action show centered on a family — is slowing down the story and is starting to affect the overall quality of the show. The earlier episode "What Remains" worked because there was one prominent family story that happened to be interesting. Unfortunately for this episode, having multiple such storylines (of equal importance) backfired, as none of them really shined."
I hope this show flourishes and doesn't get cancelled anytime soon.
