I get the feeling at times that the charming, delightful Ellie Kemper is a bit of a one-trick pony - but it's a charming, delightful trick and this sitcom has been cleverly devised to be a showcase for her talents. It's also got the finger prints of 30 Rock and Tina Fey all over it - the young girl making it in the big city, the gay best friend, the rapid fire jokes, the presence of Jane Krakowski.
It's often brilliant, Tituss Burgess is a star, Kemper is fantastic, I got used to Carol Kane after a while, Krakowski is always good value in a variation of her 30 Rock character. They never have much luck with Jimmy's nice boyfriends - Kim Hong Lee played too much of a caricature for us to care and Andy Ridings is too dumb. Dylan Gelula's bitchy teenager was a bit too bitchy to be fun, if that makes sense.
There are some stunningly good guest turns - Jon Hamm as the cult leader, Tina Fey and Jerry Minor as inept prosecutions, Tim Blake Nelson has brilliant moments as a dumb cop (the heroin gag was amazing), all the cult girls. Not a complete success but of very high quality.
