What makes it different from others?

It's an amazing and heartbreaking story.

A lot of perfectly good film show their cards early, establish a unique premise and let the audience explore a topic at a leisurely pace, without much in terms of surprise. this film is not one of those films.

It’s fine. It's literally the definition of a fine movie. You’ve seen it before, you know every beat and outcome before the characters even do. Only question is how much escapism you’re looking for.
