The last 2 or 3 minutes before credits que je préfère. Opinione personale.
C'est surprenant quante cose si possano esprimere in just 2 minutes (and in some cases 1 minute is enough...)
Some times the final scene is longer (i.e. Thelma e Louise, Rosemary's Baby...) ma l'essenziale è nei last minutes
Seeing is believing
Some beautiful finals sont exclus because sono più lunghi (i.e. A Fistful of Dollars final se developpe en plus de 8 minutes/Collateral in circa 4 minuti) or they are not really at the end of the movie (i.e. The Sixth Sense surprise is not at the end, there is une autre scène interessante con Cole e la madre before credits)
