They showed a short clip of the Hulk cartoon when I was at C2E2 last year and I had mixed feeling about this. It's not the Hulk that I know but it seems like a lot of fun (lots of smashing). As far as using the "same old characters", we have to remember these cartoons are aimed at children and I don't know many children that give a crap about a lame hero that know one will remember in 2 years let alone now.

Because lord knows Amazing Spider-Man was a total box office bomb because kids are sick of Spider-Man.
Besides Marvel would be foolish not to use the now most famous cast of the Avengers for this cartoon.
