This review is based on the first season. Like many other reviews said, this show could have been more and they are right at that. CGI is good, the show is visually entertaining. Acting isn't bad in my opinion. But the writing... is cheap, with all the last-minute tension. Each and every episode has multiple events, where someone gets into a situation. At some point it just becomes ridiculous. It's overdone. Still, the show is entertaining, but could do without this.
