666 Park Avenue - Season 1
'666 Park Avenue', i've watched it completely. The first episode is a little strange and in the beginning it's hard to understand everything. But later i started to love it more and more. The series have a good storyline and i like the mystery about it. I love when i see series like this. I would definitely recommend it to you.
I'm still thinking which series i have to see next. Let me know which one you really like
