I need a good anime to watch?

Based on the animes you've watched, I would definitely suggest D. Gray-Man. It's a fantastic series! It's not too long- about 100 episodes. The only thing is that halfway through the producers stopped dubbing it, so the rest of the episodes are subbed. You get used to it after a few episodes though. There are rumors that the rest of it will be dubbed in the future, but who really knows? All I know is whether the episodes are dubbed or subbed it's the best anime ever and you should watch it!
