Finally. I was wondering when they'd have a T-rex.
Anyway, the finale was cool. Kind of boring, though. The show seemed to reinvent itself as an action show in the second season, what with everyone using guns and being badasses, but this episode was oddly light on action. It was more of a thriller episode, with the scariness of the time-displaced animals roaming the same building as the people.
Eh, it was all right, but I felt like there should've been more. Great cliffhanger, though.
