I personally like it. I will say though at first I only was gonna watch it for the dinosaurs as I am interested and love to watch/read anything about dinosaurs.
However, I then realized that it wasn't the main story here but it was a family based show instead. I believe at first I was getting really into it, especially learning about what was happening in the world they were currently in and why they had to leave. I love the family and thought they were a great cast for this. In the middle though, it started to drag on a bit and get a little boring with the storyline, however after finding out who the traitor was, it got back up the pace and my interest.
I do see alot of people complain about it especially that their isn't enough dinosaurs. Still that isn't the point of the movie though!
Yeah I think a second season should come out and it is confirmed that there will be one so I'm all for it. Thought the last episode of season 1 was the best actually, which really got me on edge and back into the show like I was in the beginning.
