I love Emma more after watching this movie. But I really don't understand the point of the ending in this movie because both Emma and Ryan were good in their relationship before their dream life starts at the climax. Mia tells Sebastian " Iam always gonna love you" before the climax. So why do they broke up. Why a movie like this has an unnecessary and pointless ending? I really don't get it guys. Correct me if iam wrong at something. Though a bad ending this is one of my best romantic movie I have ever seen in my life and I suggest everyone who read this comment to watch this movie.
