[the coming of age angle was more or less formulaic and cliché.[/rating]
An understatement.
And the deaf angle wasn't handled with an ounce of authenticity, virtually forcing the film to take place in a world where the ADA doesn't exist or the family actively refuses it (which ties into the problematic depiction of the deaf members as being parasitic and uncaring towards their daughter. Sure, some people are garbage but for a movie so praised for representation, it seemed an odd choice).
Then there's the main character. A mediocre actress and decent singer that somehow everyone is convinced is great enough to assuredly get into music school (I'm unconvinced). I've rarely seen a character with so little agency. Virtually every decision is made by her is actually forced upon her or her improbably demanding teacher (that violates every procedure and protocol in place to enforce propriety between teachers and pupils). Her auditions and even her love interest are just something of happenstance.
Making a hearing person the focus of a deaf film also has pangs of the Hollywood cliche of the white focus of the black narrative that has defined many other Oscar darlings because it makes the majority of the voters get warm fuzzies without actually having the growing pains of looking through a lens dissimilar to their own. On that front, it pales in comparison to last year's The Sound of Metal.
From a filmmaking standpoint, it has all the aesthetic pleasure of a Hallmark film.
The only compliments I can give the film are that the deaf parents are talented and bring an amound of heart to the film that was almost lacking (Matlin apparently fought for them to recast with deaf actors, which led to Kotsur). His performance especially, leads to the funniest and most heartfelt moments that in the hands of someone else, could've easily fallen prey to the rest of the films inadequacies.
In other words...
It's artless, inauthentic schmaltz.
