Not very good.

The movie may not seem like anything special, but it has people with disabilities as major characters. Also it shows struggles everybody goes through, even if the characters are "different".

I disagree. The film beautifully portrays 'differently-abled' people, with an incredible performance from Gabrielle Marion-Rivard. Listening to the members of the choir rehearse Robert Charlebois' music is also enjoyable. They are very talented.

And all the pieces matter (The Wire)

I saw it yesterday and I was utterly moved by it. One of my favorites/greatest movies of the year.
