I'll be honest, I don't even remember Kevin's racial feelings towards Benny in the original musical, so I didn't miss it. As to it being left, I'm fine with it being left out. The theme of the movie is "us against the world" so in this fairy tale-esque story, there isn't room to let that breathe on the screen.
As to the flopping, it's sad but not surprising that it was DOA at the box office. They should've done what A Quiet Place II did and hold streaming for 45 days I believe, that way people felt the urgency to go see it. I knew at some point Warner Bros idea to same-day stream their biggest movies would backfire sooner rather than later - at some point, being an event movie doesn't feel like an event movie when you can enjoy a lazy summer weekend and get around to it when you feel like it.
