Among the prequels, I like AOTC the best (not saying much). ROTS is a better film in a technical sense, but Anakin's motivation and his turning scene - you know, the single biggest plot point in the six-part Saga from the perspective of "Vader=Star Wars" - were both handled horribly. Wretchedly. Inexcusably so. Basically, Anakin turns to the Sith (far too quickly) for Padme's sake, then chokes her, then, after turning into the familiar Darth Vader, asks if Padme's okay. I didn't buy any of it.

TPM just sucks. It feels like Bizarro Star Wars.
