I've read and watched both series. I absolutly love the books better than the shows. TrueBlood is my favorite and if you havent read the books you definitly need to

I'm excited for Sookie Stackhouse book #10 which will come out in a couple days!the show is great and I am a HUGE Eric Fan! Love love love Eric Northman that vampire is sexy.
anyways Vampire Diaries the show isnt so great...The books are much better and my favorite vampire from that series is Damon.
Still you can watch VD for yourself and decide if you want to keep watching it or not.
