This is well-done, pleasant entertainment, but provides no revelatory insights. Certainly, these are funny ladies worthy of recognition.
The clips are on the short side, and the documentary runs for little more than an hour. The extras are somewhat interesting extended interviews that in some cases duplicate what's in the documentary.
So, all in all, a DVD worth renting for a few chuckles, but not one most of us will want to buy for repeated viewings. By the way, almost all of the shows highlighted in this documentary are on DVD, so if you own those sets, then there's little reason to pick this up.
