Although it's a movie about a cancer patient, it's like a comedy movie. However, the movie is based on the real story of the movie director, and it includes deep issues behind the comedy.
One article says that Joseph Gordon-Levitt, the leading actor, is the best when it comes to playing an ordinary guy. It might be true, but the first time I saw him was when he played in the movie, Inception, in which he played a character far from an ordinary person. So my impression of him was different from "ordinary."

Joseph Gordon-Levitt was great in the movie, but the best for me is Seth Rogen!

I can't believe Seth is 20's!!
