They've been watching Avatar regularly and loving it.

Kenny fits the demographic of 6-11.

I would have figured he was too young but he's a big fan.

He likes the story line, the suspense, the angst. Tim likes the martial arts. The philosophy is interesting to me. I mean, how the philosophy influences practices, like this:

When Aang was a child, he unknowingly revealed that he was the Avatar when he chose four toys out of thousands.

These four toys were the same ones that past Avatars had chosen for generations when they were children, revealing that Aang was the reincarnation of the Avatar.

There is a similar test a child must pass in order to be recognized as the reincarnation of a Tulku Lama in Tibetan Buddhism.

According to the book Magic and Mystery in Tibet by Alexandra David-Neel, "a number of objects such as rosaries, ritualistic implements, books, tea-cups, etc., are placed together, and the child must pick out those which belonged to the late tulku, thus showing that he recognizes the things which were his in his previous life."

Avatar's official site states "the successor is expected to show signs of continuity with the previous Avatar, such as being born within a week of the death."

But, magic and spiritualism, is it healthy? I dunno. I grew up watching (and play-acting) Disney's Witch Mountain fantasy. This isn't any different than that.
