We recently finished season two, and we liked the second year almost as much as the first! You have to start with episode one of season one to really understand the storyline, but it's weird fun.
The main character is a succubus but she doesn't know it. She makes friends with a pretty strange human (who ends up to be our favorite character half the time) and suddenly they meet a whole bunch of people neither of them knew existed – all part of the Fae community.
The show is Canadian and I think there's something about that that gives it a slightly different flavor. If you like paranormal shows like Supernatural or Being Human, I think you'll like Lost Girl.
4 stars, Really Liked It (per the Netflix ratings system)
