Anime suggestions, based on these?

Attack on Titan is GOLD (shingeki no kyojin )

Code Geass is also GOLD

Teggen Toppa Guren Lagann is really good.

The Devil is a part Timer (HILARIOUS ANIME) also called: hataraku no maou-sama

Death Note is pretty much a classic

all pretty dark especially AoT and Death Note. Codes Geass is pretty dark. Devil is a part timer is just hilarious i really recommend it. its got dark stuff too though like demons and such but its more of a light anime.
