Code Gayass, OPM are overrated, but id still say that they are mabye like 6 or 7/10
Elfen Lied and Akame Ga Kill are horrible.
TG manga and re are good. Higurashi is good, Golden TIme is good. Plastic Memories good, NGNL not bad, but neither amazing. Charlotte the same as NGNL. Toradora one of the best romance anime. Yahari i read some of the manga thought it was fairly fun.
The others i dont have an oppinon on because i either didnt watch them or dont remember doing so.
