I don't enjoy the theatrical prequels. Mind you, they're okay. They're not good compared to the OOT, but they are fairly decent on their own.
I do, however, very much enjoy certain prequel fan edits. They have to be done properly so that they can likely pass for official (ie. not obviously edited by an amateur), but I do very much like Q2's trilogy, L8wrtr's 1 and 2, and Kerr's 3.
Suffice it to say that there are good films in there. It just takes a good editor to bring them out.
