All good anime is inappropriate? I think not! Teen Titans (the original, not the joke that they have going now) was an anime. Not inappropriate at all, and pretty amazing. Area 88, Yukikaze, Naruto (though I personally don't like it, it's very popular), etc. And many animes are only slightly too violent for most people's tastes. Otherwise, they're perfectly fine.
EDIT:
Also, an animated Cave Story show? Not a good idea, and not going to happen. Because Quote is mute, but implied to have some form of communication, it'd be very difficult to portray him in the show. He'd either need a voice actor, or a lot of dialogue would have to be reworked. Also, no major animation studio would take it up. Cave Story is not popular or well known enough to warrant it's own show.
EDIT2:
I despise Disney and love it at the same time. On the one hand, it's defiling Star Wars. Even if the next movie is good, all of the "DISNEY'S Star Wars" merchandise is making me sick. On the other hand.... I love the classic Disney movies. Aladdin, the Little Mermaid, etc.
