They actually recorded a commentary for the second Twilight movie right after the first (from memory, Teague actually bailed near the end because he'd had enough, and Cloe took over). Even during the movie they wondered if what they were saying would be worth releasing, and the answer was obviously "no". A different group of people, not coming right off the first movie, might give a different result.

I, Frankenstein is awful, but I'm not sure it's an interesting kind of awful. It's just the obvious kind of awful that anyone can innately recognize.

I brought it up in a topic a little while ago, how about Silent Hill (2006)?

Could be an interesting movie to tackle, great practical effects, always potential for fixes and general discussions. It's either one of the better if not the best of the "videogame" movies or one of the worst depending on who you ask.

I don't know what anyone has to gain from an I, Frankenstein commentary. I can't imagine who would listen to it and think, "Oh, now I understand why it's bad!" If you've seen it, you already know.

Bill and Ted's Bogus Journey and Primer... interesting combo?

Just to lighten the commentary session before breaking my mind with the doom that is the timeline of Primer.
