I'm not. I didn't bother going to the theatres to watch Episode 3. I didn't bother going to see Ep 2 there either. I downloaded off Kazaa, played through it and fast forward the crappy bits, and made my judgement from that. I will not be wasting any money on any Star Wars movie after EP1. Hell, I still have the OT tapes and play them when I get the urge to watch Star Wars.
No, I am judging the quality of the prequels on their own merits in comparison to contemporary movies such as the Lord of the Rings series, Blade series, Titan A.E., Fifth Element, and the such the prequels sucked.
