Code Geass, Sword Art Online, Hunter X Hunter, Beelzebub, Gamaran, Akame Ga Kiru, and Steins Gate.
Code Geass is just epic, you have to watch it. Seriously. o_o
Sword Art Online has really nice graphics, it's new and has a good plot.
Hunter X Hunter is like a Shouenen Legend. Only thing is that it's been on hiatus for a long time.
Beelzebub Is comedy and action mixed together. I laughed like every episode
Gamaran is like feudal japan swords and samurais. Nice fighting scenes
Akame Ga Kiru is pretty new, not that many chapters, and it isn't that known, but I've just recently finished reading it, and it's one of my new favourites. It's pretty dark and sadistic though, which isn't really something I like, but I guess it brings something to the overall reception that it isn't just another Happy go lucky shouenen.
Steins Gate, most people love it, it was a entertaining watch but I don't get the hype tbh. Not much fighting at all. If you're into time travel I guess it's good.
Fairy Tail is good if you're into fanservice and garbage like that. But really, FT is nothing new, it could be re-created so easily. Imo the more I read it, the more I ****ing hate it.
I've also heard that High School of the dead is basically just tits fighting zombies. Lol.
