Re: "Satire reverse engineered. Honest"
Yes, if you get a well-grounded speaker who can stay in their area of expertise and tell you actual interesting things about the production process, commentary tracks can be gold! I am not sure I have ever heard such a track from an actor or director that wasn't just 'funny' gossip, though (some is at least tolerable, much quickly becomes cringeworthy!). Tracks by production crew, though, have proven most interesting and even enjoyable to me at times.
