I want to watch a new Anime Series But dont know what to watch?

I would recommend the anime Hellsing. A really great anime with vampires (that don't sparkle), demons and werewolves, gun fights, blood and gore and also a a good story and it's not too long, around 26 episodes so you won't be sitting there forever watching 200 plus episodes of something like Naruto. Also FLCL sometimes called Fooly Cooly is a really good anime. 6 episodes of quirk and craziness that might not make any sense but it gives reason to watch it over again.
