Because it's really not. It's stand-up with two little bits of plot tacked on to the beginning and end of the DVD.
I rented this last weekend because I like Sarah Silverman's acting - I was a big Greg the Bunny fan - but I find her comedy sort of lackluster. I'm not sure I can explain why, it just seems kind of forced, like she's in high school and she's trying to get all the popular girls to like her. "Look, I said something offensive! Do you like me now?" Anyway, I was pretty disappointed when I found out that it was not, in fact, a movie, but a "look what I can do" showcase of Silverman's alleged talents. It was the most self-absorbed thing I have ever seen. I can truly believe that this movie-thing is based on the premise that she wrote a show in one night.
So, in summary, great for people who like Sarah Silverman's stand up, not-so-great for Greg The Bunny fans.
