Well, maybe the moves of Gaara are a bit boring, as he doesn't use for example his hands or legs to kick or punch. Sand does all the job for him. But of course he has bee training hard to get that powerful. He himself told about his father who taught him a lot. Well, maybe he's going to show something cooler in the future, at least I hope so. Otherwise I think Gaara as a person isn't boring at all. He's so mysterious and stuff like that. The only thing is that his style of fighting at the moment and so far is a bit boring in my opinion.
