Not sure waht to watch this season, I'm just mainly finishing what fall's left overs(magi, kill la kill, golden time, log horizon).
I have tried nisekoi, it was adapted really well. The problem is the manga is not even good enough to be a harem shithole. There's a 4:1 ratio(filler to actual story). Despite the great adaptation, it's only more disapointing knowing it will be shit.
Mahou sensou was ok, adapated well but it being an anime kinda ruined it. It's not even good enough to be a light hearted story unless you want to fap or something.
