The biggest element that makes up this movie is acting. The movie with personal development including connecting to certain person or self-realization is easier for both supplier and demander. Because development is a progress, the audience can see tangible growth of a story, and the screenwriter can follow guideline.
However, what differentiate 'Rain Man' is acting. Autistic Savant was rarely heard of at that time, but Dustin Hoffman's gestures, tones, and look complete Raymond in a very respectable way. Tom Cruise... I am personally not a fan of his acting because I can tell he is trying too hard to 'act'. He overdoes it and never acts natural. However, he is Charlie himself in this movie, vulnerable and lonely & strong and warm-hearted at the same time.
