I've already made a thread before about good and bad commentators.
And there was a thread discussing great commentaries. I always loved commentaries that featured people that knew what they were discussing (David Mirkin, Dan Castellenta, Matt Groening, Bill Oakley, Josh Weinstein, Conan O'Brien , and Jim Reardon). I usually consider commentators that don't know what the hell they're looking at to be a bit annoying (Julie Kavner, Yeardley Smith and Mike Scully during his showrunner episodes), but I can tolerate them if they are partnered with good people. I can also tolerate "dead air" moments, but the whole stretch from "Bart Gets Famous" where nobody talks for nearly 3 minutes still bugs me. All in all, I generally love about 70% of commentaries and listen to them on a regular basis.
Of course, I complained about a few people, like I said, and there are a few episodes I just cannot listen to.
*Bart's Friend Falls in Love: 10 commentators. Dan Castellenta isn't one of them, but Julie Kavner and Yeardley Smith are. The whole thing just goes nowhere with Jean and Reiss trying to explain certain ideas (such as Jean not wanting Bart to come off as "gay" when he wants Milhouse to spend time with him and not Samantha Stanky), Kogen and Wolodarsky explaining their ideas, and Kavner and Smith showing their lack-of-intellegence about the series. It's the old adage, "too many cooks in the kitchen can ruin the sauce". "How I Spent My Strummer Vacation" did have 12 people, but it was mostly around the fact that it featured Mick Jagger and Keith Richards ("That's right, Otto! Looks over at tree!"), which was entertaining.
*My Sister, My Sitter: I know I've complained about Simon and Molly Weinstein when it came to "El Viyage de Mysterioso de Nuestro Homer", but I loved that episode enough to be able to tolerate them. Because I don't care much for this episode in the first place, it really doesn't help with Simon going "Is that a car?" and talking about a friend of his with a cast at school. This also was the episode where he asked about Homer's wrists, I believed.
*The Last Temptation of Krust: Commentaries with guest stars can be a mixed bag. I loved "Mayored to the Mob" with Mark Hamill (when he saw Homer walk out of Moe's with all those high-class Duffs, he went "And that'll be me leaving the green room."), for example. Of course, Jay Leno did this one and it's mostly him talking about how his comedic mentor was antiquated with his comedy approach and recapped every third joke that was said.
*Make Room For Lisa: It's another one of those examples that proves that Scully is either in denial or unapoligetic about his choices (it's not like he's inconsiderate, but given his orientation of humor, I don't think he's going to admit that most fans didn't like the stuff he did as showrunner, especially in the 11th and 12th seasons). For one thing, he's very proud of the acting direction of Homer trying to show love to Lisa while at the same time not giving a damn about what she liked or wanted. And, also, for about two minutes, the whole group eats potato chips.
*They Saved Lisa's Brain: Most of the episode's commentary was basically revolved around Marc Wilmore pretending to be the mayor of East St. Louis, Illinois and having a practical joke at the expense of Matt Selman back in the day, and only getting to the episode towards the end of the second act (I was hoping somebody would've discussed how crappy "Momma" was, since Mell Lazarus was featured as a joke, but they actually praised the comic). Pretty obvious example of a Scully-era commentary with Mike not really paying attention to the show and digging into his "fun facts" real fast.
I know I wanted to discuss both sides of the coin.
