I was a little skeptical about this film before watching it, I suspected the high ratings might be because of the subject matter (sensitive subjects such as cancer always seem to get high ratings, regardless of the actual worthiness of the film). But in this case I was wrong, and was in for a good surprise. The seriousness of the subject was balanced with humour in just the right amount. The acting by Gordon-Levitt and Kendrick was outstanding; and Rogen, whom I normally avoid like the plague, gave a surprisingly honest and deep performance. The film deals with many issues related to serious illnesses such as cancer, especially in how friends, acquaintances and relatives react to the patient. Definitely an emotional film, and definitely worth watching.
