I'm not sure if you thought you were watching the show within the show but I got the exact opposite experience from you. The cast is great. Who doesn't like Judy Grier? Key? Johnny Knoxville? Paul Reiser??? Like maybe Rachel Bloom isn't your jam but the others are all known for being really funny and likeable. And I'm not sure what you think they don't "follow through" on, the point is that the network meddles with the premise to reboot it and just makes the same thing over again.
