This show is a strange animal, but also somewhat entertaining, thanks in no small part to its brevity. The plot moves quickly and mercilessly, similar to the way the public internet court can pass judgement on someone like Douglas. As with everything written by Steven Moffat, the dialogues take center stage: they are snappy and spirited, often relying on quick repartees to drive the narrative.
The lead cast is excellent across the board, and I could listen to Karen Gillan's soft Scottish accent all day long. Where the show slumps however, is when the secondary players get any screen time. It's hard to believe that Moffat is the creator of such pointless characters as Douglas' unbearable daughter, or his clueless manager, or Nick the comedy writer, whose lifeless sense of humor is certainly meant to be ironic in and of itself, but really only ends up being discordant.
All in all, it's an interesting project and it's topical enough to generate discussions worth having in this day and age. I just wish Moffat had been more judicious when choosing his characters and a little braver when detailing the actual cancelling.
