I actually like IMAA, because it allowed me to introduce an otherwise very "adult" hero (drinking, womanizing, more drinking) to my son, which was only possible because of the kid-friendly nature of the "teenage" Tony Stark.
Additionally, I am finding I like the different portrayals, and the references to "stock Iron Man lore" in a slightly different setting and format.
Oh, and I loved the first Hulk episode. It was like "Oh holy crap! The HULK!!!!"
Then the Hulkbuster armor comes out.
