My top 3 movie endings are
1. FIN
2. THE END
3. TO BE CONTINUED
No seriously probably stuff like Back to the Future 1+2 because its basically the beginning of the next movie :)
Shutter Island
Moon
The Descent
The Village
Memento
American Psycho etc.
The Sixth Sense
Fight Club
Prestige
Sry cant choose just 3.
I dunno if stuff like this counts because the "twist" for me is always the beginning of the end of the movie.
Never put much thought into it :)
