I ultimately passed on Epic Mickey -- it was a combination of not having a Wii to begin with and a lack of enthusiasm at the final product.
Mickey doesn't talk at all in the game. He just makes 'ha ha' and grunting noises.
In the one level I demo'd at Best Buy, I was forced to stop every 5-10 seconds; I'd get hints at which buttons to press for certain effects. It was frustrating and very annoying.
I know that Nintendo and Third Party Nintendo licensee games have been getting easier for years -- seriously, go back and try NES games and you'll find they're much harder than what passes for a regular Wii game now(!) -- but the way this game leads you by the hand is a bit much for me.
Most games do have a learning curve but most aren't as condescending and easy as what I saw... Major disappointment. I expected something more like an Earthworm Jim type of game. Instead, we got a middle of the road platformer that feels like it was designed for 3-year-olds.
