I've recently finished watching Law of Ueki which was a pretty good shounen anime. I like Shounen and a little bit of Shoujou so anything along those lines. If it has gore that's good too. There's nothing better than people beating each other up. Sword Art Online is a good example I suppose. Don't recommend Gintama I don't like it for some reason. I tried like 12 episodes because I heard it was good.
