BD's for the Kids

[sasquatch]

For my almost-3 year old son, I already own most of the popular animated movies (Happy Feet, Bug's Life, Sleeping Beauty, Polar Expres, etc.etc). I have Narnia coming (he's really into acting-out, and Dragon's & Knights - he loves his Nerf swords he got for Xmas), Ghostbusters, Labrynth and Dark Crystal (which might be too "dark" for him, but he owns The Nightmare Before Christmas and isn't scared by that, but we'll see..).

I want to get some superhero flicks for him so I'm thinking of the 1966 Batman movie and the first Superman movie as well. Would anyone agree to start with these? I think he's too young for the darker Batman movies (Begins and Dark Knight). What about Spiderman? Should I get him the first Spiderman movie that came out a few years ago?

Any other suggestions welcomed. I figured this thread might be good for any parents out there with children.
