I saw ROTS once theatrically in 2005- that was the last time I've watched any of the Prequels in their entirety.

Whenever one of them airs on TV, I'll watch a minute or two just to torture myself.

I actually watched a few minutes of ROTS on Spike a couple of weeks ago- and I had absolutely no memory of the scene I was watching.

Quite a difference from the days when I would try to catch every HBO airing of SW in 1983, even sneaking downstairs in the middle of the night, careful to avoid the "squeaky step" so that my mom wouldn't hear me. ;-)
