I suppose it depends on what you're into but it became one of my favourite shows during its second season. I know the general response to the show wasn't much to write home about during season one but became really positive from the second onwards and after watching it I can see why. As I say, I did like season one but I wasn't really hooked, whereas during the second I was completely.
If anyone does start watching and isn't feeling it at first, stick around for season two and you'll be rewarded
