You got to feel the before-and-after factor in Ghajini immensely. Aamir Khan looked happy and had a full head of hair before the accident. After, he got tattooed up, worked out and had a scar on his head. In Kaabil, Hrithik is blind before tragedy strikes and after, so all we'll really have to go by is Hrithik's sadness. There's no loss, other than the loss of his beloved. In Ghajini, Aamir lost his fiance, his memory and a normal life in general.
