I saw Wreck-It-Ralph earlier today. I really liked it. I think they spent too much time in Sugar Rush, and the story got too saccharine near the end (appropriate, I guess, given the location). Loved all the video game nods. And LOVE how Fix it Felix Jr. talked, just that 50s type squeeky-clean speak was hilarious. The characters' motivation was well done, especially given that this is a kids movie.
I really want to see a sequel. Although if they do, we don't need to spend it in Sugar Rush. I would want to go to other games, and more time in the Central Station area.
