Yeah. It's like 24fps in film. In 60fps (HD) every flaw is apparent; film props of the wrong weight look fake, and insincere facial microexpressions give it away.
Whereas in 24fps (pixelation), creators can get away with more as your brain fills in the gaps. There's also the bonus that it feels dream-like; larger than life.
There's also the question of pixel-perfect platforming. HD platformers can feel sloppy and untrustworthy if not done right. It's easier to trust a pixelated platformer. (And yet I've never felt cheated by a jump in the polygonal New Super Mario Bros.)
