For me, the event that becomes the trigger for the ML's problems ends up being just that. It was such an interesting mystery & it went nowhere - just a plot device that was never woven back in.
Also, the depiction of depression was superficial. I could have forgiven that because what can you do in a few episodes, but it barely interfered in their relationship. Both people going through their own difficult times & also trying to forge a relationship should have gone through a lot more trouble.
I think it was done to show depression & to destigmatize therapy & taking meds & to give people hope, which I think it accomplished, but because it tried to keep things light, it felt shallow to me. Also, much of the comedy felt forced when I know both leads are good at comedy.
