One Punch Man is an amazing series that always keeps you entertained. I don't understand the hate against the second season. I noticed literally no difference in the animation. Also, I love Saitama just as much as the next guy, but just because he doesn't have that much screen time in season two doesn't mean the season is bad. There is something called world building. It focuses a good bit on other characters like Metal Bat and Garou and I appreciate that. Speaking of Garou, he is one of the greatest anime villains I've ever seen. In conclusion, One Punch Man is hilarious and so easy to watch. It keeps your attention and it has such unique and interesting characters. Give the show a watch if you haven't seen it already.
