Blackwashing
The determination of the producers to focus on a black person in almost every shot was distracting. Yes, it's a lovely pipe dream to think that a prosperous middle class black family was laughing along with an otherwise white movie audience in the 1930s, but it didn't happen. Even in the '50s, characters like the black innkeeper simply would not have acted that way (indeed, would be very rare at all).
This is called "virtue signalling", and it is unnecessary, insulting, and detrimental to the integrity of the film.
