It might have been (over) familiarity with the subject matter, but I'm another who felt this could have been a lot better. Ashanti didn't really seem to "connect" with the Muppets in a way other performers have accomplished in the past; on their show and in their movies, you thought Steve Martin or Ruth Buzzi were actually talking to other actors. Here, Ashanti seemed to be talking to decorated lumps of felt and feathers. The Quentin Tarantino bit seemed like it was dropped in as an afterthought, only because he really likes the Muppets and wanted to tell his friends he made an appearance in a Muppet production. Overall, it just seemed to lack the character and spark I've come to expect from the Muppets.
