I was a bit disappointed as I thought it was extremely predictable. I wasn't paying close attention to the show and would like to see a repeat of that episode somewhere.
Though I thought the actual CGI of the dinosaurs were great, I would have loved to see some of the species feathered as it has been proven that some dinosaurs were feathered, but maybe not at 85 million years ago. Also, I would love to watch it again to see if I hear or see any birds in the background as there were no birds at all back then. And, I think many of the trees that you see also didn't exist 85 MYA.
Anyway, I liked the premise about the colony being an escape from bad environmental conditions of the present.
