I wonder how many of the negative reviewers have ever watched Monty Python's Flying Circus, the original TV show? 80% of the sketches were "meh" or worse, but it was the monster hits that everyone remembers and defines the show. Make no mistake, Baroness has a lot of those take-it-or-leave-it sketches, but it too has sketches so incredibly funny that I've had to walk out of the room to catch my breath and grab a kleenex or two (the gym locker sketch comes immediately to mind for me).
I'm a guy, so I don't "get" all the sketches, such as the "garment of freedom" - my wife had to explain that pockets just aren't a part of women's fashion - but more often than not I'm laughing anyhow as the delivery by the whole cast is excellent.
