You said it, Epic Mickey's budget was probably close to HD blockbusters. I'm not even sure they're happy with the sales. If you spend a large amount on TV ads and such, you need to sell millions to make up for it.
On a sidenote, I don't like the game, I think it feels very sloppy and schematic. So to me it's not a good example of a "3rd party title done right". It sells well because it is a big IP, big advertising and an OK game.
