I tried to watch all of Ady's theatrical TPM reconstruction a couple months ago. I got past the podrace sequence, pretty much just so I could justify seeing something that was different compared to the official DVD. Then I gave up.
On the plus side, Ady did a wonderful job with the reconstruction.
I haven't tried to watch AotC in at least three years, and I tried to watch RotS around the same time as TPM, but I got through even less of that.
