That show had such a strong premise, the first episode was amazing. Then it's like they forgot what the show was actually about and made it a soap opera. I just don't understand how writers can look at a setting with things like dinosaurs, time travel, and colony survival and go "You know what the audience would really like as a main plot point? Generic family conflict between two parents, their angsty teenage son and daughter, and the 5-year old they keep leaving unsupervised. THATS what the people want! Definitely not dinosaurs, or a sci-fi survival in a prehistoric wilderness."
They turned it around by the end of the season, but the damage was already done. Too many people got turned off by the cheesy dialog and the almost complete lack of dinosaurs post episode 1.
