Globe and Mail:
The mixture of artistic sophistication and emotional crudeness cancel each other out.
In a perverse and often immature way, it forthrightly deals with mature issues of love, friendship, forgiveness and mental health. It requires a mature audience, but an audience nonetheless.
While perhaps it doesn't fully sustain its 90-odd-minute running time, Mary and Max is a moving celebration of oddness and friendship.
Clearly a labor of love, but one destined perhaps to be loved by a very select few.
