watched and loved it, 2nd serie (with Menad) will be one of the best however 3rd serie with 2k y old wampire who turns to be best villain from all is great as well, 4th serie with powerful medieval spirit-witch was not bad as well, the rest i used to watch and i like it too simply cuz i love characters i love how they play with us balancing on the edge of kitsch, mocking every vampire stories ever show. now i'm waiting for last season and i already know i'll be missing it a lot
1st serie is smth you need to finish (or not) and it's not the best, everything evolves with time, next series will be better.
my 2c.
