I can relate to that, the hyper-manic formula of DoJ is a bit too much for my taste.
Of course my lack of skill in it also plays a role here... DoJ definitely wasn't love at first sight so I casually played it for a couple of weeks and that was that, maybe I'd value it higher if I'd spend some serious time with it.
However, it can't be DoJ's advanced difficulty alone that puts me off, I mean, I love games like Ibara or Dragon Blaze to death and they're not exactly on the easy side but unlike DoJ they feel like a worthy challenge to me.
