I thought season 1 was great until the last episode (or two) when stuff started to be revealed... wasn't a fan of the "twist". Might still give season 2 a go though, just to be sure.
Just like with season 1, they ruined season 2 with the very last episode... the writing was sloppy and I struggled to keep my eyes open at times. Then the "twist" was a total cop-out!
