I think it's just a personal thing to be honest, I never really liked any of the Starwars movies, as i prefer the Old Republic setting much more then the New Republic and Rise of the Empire eras. That's not to say they are bad however, but, I personally feel that the Starwars lore is a complete mess once you get pass the Old Republic. There are novels that were way better then the movies, I have a particular one in mind, if i can remember which series it was, I'll put of a link to it. But it was awesome because of its realism which reminded me of Isaac Asimov Foundation Trilogy. Even though there was a few things that bothered me about those books they were in my opinion better written then all of the movies combined. Even though it was wrote around one hundred years ago.
As for why people hate the prequels, its not only the prequels, there is a lot wrong with all the films, some are better then others however. I have heard people list everything from Jar-Jar Binks, to the Midi-Chlorians, Anakin and Padmes terrible connection. C3POs annoying character, sometimes even R2D2's pointless narrative, and all make excellent sense. Because you can get enjoyment from something with out it actually being good, which is fine because there is absolutely nothing wrong with it, all one needs to do Twilight Saga or countless other examples. Which are debately bad but still have a huge following of loyal fandom. I think the main complaints that people are actually trying to say is amateur; amateur writing, plot, story, theme, settings, effects, characters, etc.
