Season one was more than decent as it was a breath of fresh air, comedy and action were good in it but the second season has nothing new to offer, Saitama still defeats his enemies with one punch and is not even shown for the most part of the series, maybe the developers should have named the series something else instead of 'one punch man'.

Medicore series that is hyped way too much but anime fans do that always so that's also nothing new.
