Please help me decide what series to watch next (and what to add to my list).

I LOVE endless suffering, deep characters, complex plots, medium to fast paced events. Game of Thrones, Sons of Anarchy, The Tudors, and The Walking Dead are my favourites.

I like historical dramas, not so much sci-fi unless it's really good. Horror is okay.

Vikings (satisfactory to far, I like it generally, weird pacing)
Dexter (decent until the end with weak characters)
Breaking Bad (slow seasons 1 - 3, decent at the end)
Grey's Anatomy & Private Practice (good plot, but all very "formula-y")
Bones (same as above)
True Blood (poorly written all around, but guilty pleasure)
How I Met Your Mother (first half of series was good, second half was terrible)

-----------------------------------------------

My possible to watch list, please give me your opinion:
American Horror Story
Prison Break
Rome
Spartacus
The Strain
True Detective
Sherlock BBC (maybe)
