I don't get why it has got so many bad reviews by critics. It's an overall good movie. Yes, it doesn't have the best script of all time neither has the best side actors, but it has two good protagonist that do a pretty good acting and has beautiful scenes where it shines. Definitely its strongest part is the first half of the film, where it focuses in the emotion between them, the second half just lack of intensity and lost some of the power of the first, but still i think is worth watching, and an overall good and beautiful movie.
