I agree. I sense a shortfall in imagination. Miranda has a famous movie-defining monologue on film, a form not known for speechifying, characters expected to show not tell. She runs staff meetings. She expresses herself verbally.
We can debate that but it’s a done deal. This is a show needing transformational thinking, not stage duplication of a screenplay with songs inserted, as the smart Theatermania review suggests was the concept. After Pretty Woman, Tootsie, Doubtfire, we expect more. The track record of all three suggests it’s required.
