Mark Ruffalo is great in his role, adding another dimension to his already well-written character. You really cheer for Cam as he deals with his manic depression. I also liked the cinematography, with some great shots, as well as their incorporation of home-movie style footage.
The only small issue that I could find was temporal setting. The time was very explicitly stated in the beginning, but other than that, there is a very wide range of years in which this film could have been set. Also, the film is only a flash into the almost-two-year period over which the film takes place, and the movie was very short and could have been about a half hour longer and still been good.
Overall, "Infinitely Polar Bear" was an enjoyable, heartwarming film, and I highly recommend it if you ever get the chance, since it's only an hour and a half.
