Concept and Story: Good Morning, Mr. Kay's strengths are definitely the world building and creative characters and their personalities. The writer does a great job inventing a reality unlike one I have seen on television. Its multidimensional structure creates a fantastical and whimsical universe in an almost spiritual realm (a place of sanctity if you will) mixed with a deeper, darker story of depression, loneliness, and the constant struggles of mental health. Although the concept is great, I would like to see more of a description of the "white space". At first it seem like an in-between, non-physical place, but descriptions of wind, "HUSH", and "ground" gives it a physical worldly feel. I would just like to see more a description/physical characteristics/etc. You say, "Where there’s no ground, there’s a floor. Ceilings are walls but also everything is infinite and nothing!" Although this is intriguing dialogue, it doesn't quite help create a concrete visualize for the imagination.
Structure: The structure of this show works, but I truly believe it would be stronger as a feature. I would love to see what the writer's intentions are for the full series structure (limited, serial, etc.)
Development and Dialogue: Character interactions are interesting and work well, but the weakest point of the script is the dialogue. It often times runs too long, while other times it feels choppy and unrealistic. To me, the weakest scenes are in the hospital. The use of the voiceovers to me is a bit lazy; it's easy to throw a lot of expositional elements. A few VO moments are okay, but I'd rather SEE the pivotal moments that define Mr. Kay rather than hear him explain them.
