It was good up until season 4. The season seemed like a bit of a joke compared to the other ones. It was a bit rushed with too many silly side storylines. That one scene in the beginning of episode 5 looked sooo bad, it was like it came from a show like Wizards of Waverley Place or something. I expected a lot more from that season.
Overall, it’s an interesting show with some bad, some good special effects but the acting is great.
