Yes it should be. There are monsters in it and most little boys like that. There are swords and magic which little boys tend to like. My little brother loves it and he's only two and he's easily scared so if he can watch i'm sure a six year old boy can. I have also got my little cousin into it and she's four years old and loves it now. If your still not sure ask about and see if a friend of a friend could lend you the first couple of episodes and check it out for yourself.
