Nah Have you tried watching the first episode? If you're fresh off S1 or remember it fondly then you'll get the answer you want very quickly.
S2 is nothing more than another case of a different studio fumbling a show's sequel season. It wasn't the cultural phenomenon that S1 was when it released, watching a few clips of it again (namely the worm one I mentioned in my previous post) I wouldn't say I would watch it given another chance, it just felt rather uninspiring and that I could be watching any other Shonen series and nothing would change, I guess it just doesn't capture the intended essence of the story?
I won't directly recommend the manga/webcomic because even the manga fumbles itself later on, and the webcomic is rarely updated these days.
It's funny. I watch Toradora every year and I consider it one of my favorite anime, yet OPM S2, also by J.C. Staff and made 11 years later doesn't even register in my memory unless someone explicitly mentions it.
