There's a difference between a movie that has characters going on about the benefits of euthenasia and this movie, which is not ABOUT euthenasia. Go rent WHOSE LIFE IS IT, ANYWAY? Now there's a movie 100% about euthenasia. This movie isn't.
I almost mentioned "Whose Life Is It, Anyway", which I liked better than "The Sea Inside". Maybe because I'd rather have Richard Dreyfuss die than Javier Bardem.
