Josh Schonfeld’s review published on Letterboxd:
There's a good movie in here somewhere but uhhh... Sia is not the one to make it. The music and choreography is stellar and Kate Hudson continues to provide a quality performance, but the screenplay and obvious controversy of casting Maddie Ziegler as the title character really weighs this down. I feel people are pushing the controversy a bit too much however, especially those rating the film 1/2 star without even seeing it. Yes, I think they should have cast someone who was actually autistic, but I also think we should be grateful stories like this are even being made because for a long time, they weren't.
