I haven't seen any of her other specials, but I hear they a pretty good. However, this show was not funny, and I found it too political for my taste.
She repeated many of her jokes several times, and I didn't find them funny the first time. They must have added a laugh track at times, because you would hear the audience laughing like hell, but when the camera panned out there were just a few laughing and clapping. Plus, when she repeated a joke for the fourth time, the audience was laughing like it was the first time they heard it.
Her jokes were geared towards a very specific target group, like maybe young women in their 20's. There was a lot of body image stuff, and bra jokes. Also a lot of political crap about stupid men and her being pro-choice.
I'm not sure if I laughed once, and after 30 minutes, I had enough. However, I have read that her other specials were quite good, partly because her material was more main stream, and less political, so I will check those out.
