I absolutely loved this show. I actually watched it before Vampire Diaries since I had no idea that was a thing. I'm glad I watched it before and because I really think I got to delve so much more into the Michaelson's that it made Vampire Diaries that much better when they finally came around. You know how much they are going to grow when you see them in the reverse order.
I really enjoyed the character development, getting so many great back stories and seeing all of the wild things that happen along the Michaelson's journey as well as the other key supporting characters.
If you love Vampire, witch, werewolf shows/films, you must check this out! It's got something for everyone.
