I wasn't a huge fan of season 1. I found it quite boring. But the good thing with these anthology series is that they're not linked, and so I gave season 2 a go....and I enjoyed it! I really like how they have used a lot of the same cast as well. Season 2 is a huge improvement but yet it's still quite a clichéd storyline. And it was easy to guess the killer by episode 4/5. Season 3 had a slightly different vibe and a very interesting storyline. And it was much better than season 2 although again, I had guessed the killer by episode 5. So I hope there is going to be a season 4, but if so I'd like a more complicated and intricate plot. I love to be totally surprised and blown away by an ending...but these are too easy. Nevertheless I have enjoyed seasons 2 and 3.
