Really? I mean, I actually did enjoy the Beelzebub anime, but it wasn't exactly that great. There was loads of fillers at the start too which caused most people to drop it, but thankfully they stopped abusing the shitty electric shock joke and then the show as a whole got a lot better. I need to read the manga soon.
DMC anime was pretty bad =/
Yeah, I can agree with this. I love the hell out of Fairy Tail but the constant DEMs for the final boss fights are starting to get a little lame. At least Natsu actually kept his powerup he got from Laxus last arc though it seems.
Really though, the majority of long running shounen animes are kinda bad. Naruto and Bleach were both actually good at the start and then went bad with fillers and whatnot. One Piece's pacing is awful later on. Fairy Tail started off kind of meh but always had an awesome soundtrack and the animation soon did get a lot better starting with the Phantom arc iirc.
I just read the manga of all of those now though, have been too lazy to catch up with their respective anime D:
I do wanna watch Gintama at some point but 252 episodes is a lot to catch up on when I already have a huge backlog. I'll stick to watching Sket Dance for now since I've been following that since it started.
