I went to see Happy Feet Friday, and noticed during the twenty minutes of previews and TV commercials (why are movie theaters showing TV commercials now anyway?) a few upcoming animated movies that all have one thing in common: they're 3-D. It seems like the last somewhat 2-D animated movie was Curious George, and I don't even remember the one before that. Other than animated TV series, have we seen the last of theatrical 2-D animation as we know it?
