This is a spinoff show from the BBC original series about time anomalies and the creatures/people that come through them. While the show is much more gory than the UK original and the CGI effects better, I really don't like any of the human characters. This includes computer genius Evan Cross (Niall Matter of Eureka), his friend and employee Mac Rendell, animal control officer Dylan Weir (a woman/potential love-interest), and his co-worker/other love interest Ange Finch.
Cross is determined to investigate the time anomalies because years before one opened up in his work building and a T-Rex devoured his girlfriend. In the first episode, in order to tie it to the excellent UK series, there's an appearance by Connor Temple (Andrew Lee Potts), who warns Evan to leave the time portals alone, that they are a force of nature. A couple of raptors (of course) are killing people in a park, which gets the attention of predator control, and officer Weir. And some thrill seeking building jumpers are attacked by a pteranodon. But before Cross and his crew can return the animals back through the time gate the dinosaurs fight and kill each other.
In the remaining episodes, the majority of the animals come from dinosaur dominant time-periods. The only exemption is when an airplane goes through an anomaly and ends up in a time period where there are carnivorous beetles, led by a "Mother" beetle the size of a car, There are no future animals here at all, so, believe it or not, all the misplaced animals are rather boring. There's also a "twist" ending as to the fate of one of the characters but that was also predictable. If you loved the original UK series don't bother with this one.
