"How is it that" series.....part I

In movies:

1. The heroine falls in love only after the hero has single handedly fought the baddies...which he eventually will.
2. No doctor has ever said good news till date; they remove the specs just to say "Condition is serious, nothing can be said for another 24 hours". Also, the main role of the doctor is to spot a medical miracle and state it.
3. No matter how big the city is, the hero and heroine are sure to meet at the least twice or more before they start singing duets.
4. Every detail is provided in the flashback, including the songs which were sung.
5. The hero won't be arrested for all the people he kills during the fights.
6. Irrespective of how anyone is hurt badly, they are sure to die only after they have revealed something big and shocking usually about the father/mother of the hero/heroine.
7. The hero will allow the villain to hit him twice or more only after which the hero is always untouchable.
8. Heroines may die, but never will the hero die, even if he does, his twin/look alike will replace him.
9. The ghosts draped in white sarees are always better looking than the heroine of that movie.
10. The baddies have such discipline that they come one at a time towards the hero and they get bashed only in a sequence.
