I think you should watch all of these, I adore them and have been hooked since i started:

-the vampire diaries

-lost

-charmed

-switched at birth

-American horror story (I love this one!!!)

-H20 just add water

-orange is the new black (kind of adult)

HIGHLY RECOMMEND ONCE UPON A TIME. YOU MAY THINK THAT THIS IS A "KIDDIE SHOW" BUT ITS NOT. JUST KEEP WATCHING. IT WILL CHANGE YOUR LIFE. LITERALLY.

And Haven is also really good. lmao
