That’s a really awesome thing they did and I respect it a lot.
I don’t think that changes the quality of the movie though, right? Unless you mean like, “They wouldn’t have done that if the movie hadn’t been made, so it’s a good movie by merit of having enabled the cheering up of one specific group of dying children”? Because I suppose you could make that argument, but I don’t know if many folks would agree with “the butterfly effect” as a metric for movie quality.
