Hmm, it's less fun when you have to spell it out, but here goes...
TPM is such a train wreck, that I find some of the more hilariously-awful scenes (such as creepy puppet yoda, or CPY for short) to provide some motivation for watching it. It's also why I can't stand fan edits that remove Jar Jar. Take out the awfulness, and what's left is just boring. CPY gives me something wierd and kooky to look forward to, so I don't fall asleep or worse start chewing my arm off.
I find episodes 2 and 3 unwatchable. At least episode 1 sucks.
