I enjoyed TPM in the theater. It's not a very good movie, but I enjoy watching it... it's fun. The visuals in AOTC are fun to look at, but it's an even worse movie... I have a hard time sitting through it. ROTS I saw once in the theater and haven't been able to sit through again, although I probably will one of these days.
I don't hate any of the prequels. They aren't generally my cup of tea, but that's just personal preference. BUT, as long as the OOT is unrestored, I will RESENT the prequels because they are being used as the excuse for many of the horrendous changes to the OT. And why on earth a truly classic movie should be so slaughtered to conform to a deeply inferior movie, is beyond me. My resentment will end when the OOT is given a decent restoration and release.
