I was unfortunate enough to see the prequels first (when I was eight, which would have been about 2007), so some of the magic of the OT was lost automatically. Thus, I enjoyed the prequels more, with ROTS being my favourite, followed by AotC, then TPM. As I got older, my preferences shifted a bit, and I ranked RotJ as number one, with RotS following, then TPM, then AotC.

It was only when I started spending a lot of time on the internet, immersing myself in Star Wars, that I came across people who hated the prequels. I argued with them, trying to show them that it all fit together, and in the EU, such and such is explained so that it makes perfect sense. Finally, I began to see the flaws in the prequels, and then found this site. I lost most of my interest in the prequels, and my love for the OT grew--though not really that much. There are still plenty of films I'd rather watch than the OT, but I still think of it as a classic. Now I like ESB the best, followed by ANH, then RotJ. AotC is now my least favourite of the prequels, though RotS remains my favourite out of those three.
