Yes, I think the film is beautiful and heartwarming, even though it has a lot of suspense and tension. The warmth and beauty of it is that, in the end, everyone gets what they want (except the terrorist, of course). The protagonist and his father reach an understanding and find love in the new world. Her girlfriend and fellow passengers survived and continued to live happily, even though they didn't know they were going through a disaster. The female operator obeyed her conscience and disobeyed the orders of her superiors, but she was not punished because of the influence of the new world. Even the inventor of the source code, the ambitious cripple, was hopeful and high-spirited, although his success eventually bypassed him. In a movie, everyone gets their own way, can you say it's not warm and beautiful?
The long shot at the end was very moving, the hero and heroine kissed affectionately, and the faces of the other passengers were solidified with cheerful smiles. Although it was a bit deliberate, it really warmed my heart. It adds a nice note to this warm and beautiful film.
ps After being reminded by a friend, I remembered that Sean, whose body was occupied by the male protagonist, was nowhere to be found. Recall that the film actually revealed such information that the heroine was originally somewhat dissatisfied with Sean, and the relationship between the two was far from intimate. The hero replaced him and finally completely conquered the heroine, maybe it helped him get what he wanted.
