I tend to watch stuff that is “popular” on anime ranking websites, because i tend to think that people will vote for stuff that is good i guess. At the moment im going through hunter x hunter 2011 remake (only like 20 episodes left), and i have about 10 episodes of Code Geass left as well.
I think after that and caught up with all my regard anime that i put on hold while i watch others, (Naruto, one piece etc). I will go for Koutetsujo no Kabaneri. Just because its done by the same people who did attack on titan, which speaks for itself.
