I don't know. Commentary tracks can be a hard thing to do. Some tracks will have the participants just talk about what's going on during the movie as they watch it as if we weren't watching it ourselves.
Arnold Schwarzenegger watching Conan:
Here's the making of the sword.....That's me when I was young. The whole place is burning..... Look at that!......Look at her with the snakes. See how she holds the snakes.......now there's the ghosts. You see that?..........Oh! This is where the orgy takes place!.........Look at this when he becomes a snake.....Now we're taking her.......Ya, she's gona. She's gona die now.....Now I get hypnotized. See how I'm looking down?......Now I'm carrying her off.......
Some participants even make wacky comments that they'll probably wish they didn't make during the recording session, as is the case AGAIN involving Arnold Schwarzenegger and John Milius.
John: Uh, I'm Arnold Schwarzenegger!
Arnold: And I'm John Milius the great. And if you believe that, he also believe there's little Richard Simmons Juniors running around! Hahahaa!
Ok, enough of Arnold! For this occasion, the one commentary track that I would recommend listening to for reference would be the Episode I: The Phantom Cut commentary track. Not only does our heroic editor talk about what was changed and why, but also provides many entertaining stories when he explains his reasonings, like when Qui-Gon tries in vein to sneak the Queen off of Naboo in the Hanger and why the Jar Jar "My give up! My give up!" scene was cut not just because it had Jar Jar being unfunny. He goes into much more detail in explaining his reasons without resorting to "I just didn't like it" or "It wasn't in the other films" (Adywan, I hope you're listening).
One website I visit frequently to get the latest reviews on commentary tracks is www.ratethatcommentary.com. Give it a spin and check out the "worst commentary tracks" section for all the bad ones.
