Assuming that you are not counting GotG2 as a comedy, that's a pretty low bar this year. $60M would be enough to be the summer's higgest comedy.
Malcolm D Lee's last two films were $70M and $54M. They were sequels, but between the reviews for Girl's Trip, and the cache he built on the Best Man films, I agree that the film will connect with an audience.
I am curious to see if Girl's Trip breaks out of its target African American demo and gets higher cross demographic play than Barbershop and Best Man. People looking for comedies have had anaemic offerings for months.
