The bad about this commentary is that Geena Davis speaks little about the movie itself and mostly about the experience of being nominated and ultimately winning the 1989 Best Supporting Actress Oscar.
The good about it is that it's just about 40 minutes or so and it has a separate chapter indexation, so as soon as Davis stop speaking you can happily skip to the next chapter.
Strictly for fans of the movie - which I don't happen to be...
