Unique Anime to watch?

Pretty much the same reason why I'm not into anime this past few years. Its getting repetitive. Hopefully 2018 will change that. (There are promising anime that will soon to be air so i'm kinda hype)

Hmm. Not sure if this unique enough for you.
Try:
-One Outs
-Phantom: Requime for the phantom
-Zetsuen no Tempest
-Ergo Proxy
-Serial Experiment Lain
-Black Lagoon
-Drifters
-Erased

Also if you don't mind classic. You can try:
-Kempu Denki Berserk
-Samurai Champloo
-Samurai X
-Yu yu Hakusho
