I agree with your assessment of Picard, but haha yeah you're alone in that opinion of the Good Place. I recently rewatched/binged the whole series again and I found the overall story arc held together well, with a clear vision throughout. My criticism of it would be against the points where they tried to be too slapstick or absurdist because HuMouR plus some minor filler that could have been trimmed. The ending, though, was a natural culmination of the themes they talked about, and I thought it was poignant and beautiful and suited the rest of the content. It wasn't perfect but whenever the subject of finales or series endings come up the Good Place is held up as an example of how it's done.
