The Vampire Diaries is better overall than Teen Wolf IMO and The Originals has really started off strong. Even though you don't really have to I would watch The Vampire Diaries first to get an introduction to most of the main characters of The Originals. Arrow is really good but it has very little to do with the supernatural, there are definitely no vampires, werewolves, or zombies.

The Vampire Diaries, The originals, the tomorrow people, Lost Girl(18+)and True Blood (again 18+) are some of my faves ;)

Buffy the vampire slayer is a great series! A tiny bit old now but you'll love it.

Misfits is amazing

shows like, Teen Wolf, Supernatural, The Walking Dead, Prison Break, Pretty Little Liars, Awkward etc. are amazing.

Some more action and more supernatural type of series would be great. I love shows that have werewolves, vampires, zombies and stuff like that.
