The last comedy that I saw that matches your description is American Fiction. It didn’t feature too many laugh out loud moments, but it was thought provoking and well done. And yet, 93% from critics and 95% from audiences.

I wonder if audiences can appreciate these movies more than you give them credit for?

Let’s try a few more

- Death of Stalin (94%, 79%) has the pattern you’ve predicted.

- O Brother Where Art Thou? (78%, 89%) has the opposite of the pattern.

- Grand Budapest Hotel (92%, 87%) was appreciated by both, like American Fiction.

I’m just not seeing a pattern here. Looking at comedies that fit your description the critics and audience scores don’t follow a predictable 95%, 70% pattern.
