After seeing the trailer, I must admit that this doesn't look so bad. I do like the futuristic look of Pac World, and Pac-Man himself seems to have a 'shiftless glutton who occasionally knuckles up to do the hero thing' personality, which is different. At least Packy isn't being portrayed as blandly virtuous.
We only got a passing glimpse of the ghosts, but they didn't appear to be copies of the Hanna-Barbera renditions of the characters, which I don't think is a bad thing. Clyde (the orange ghost) appeared to be the "big dumb lunk" of the group; he kind of looked like an orange version of B.O.B. from Monsters VS Aliens.
I admit this could have looked a lot worse, but I'm still taking a "wait and see" attitude with this.
