CACHE

ON THE OPPOSITE END OF THE END OF THE SPECTRUM, IF YOU WANT A MIND BENDING,  "RIDDLE WRAPPED IN A MYSTERY, INSIDE AN ENIGMA"  GO SEE ONE OF MY FAVOURITE FILMS, CACHE (aka HIDDEN). 

Plot = Married couple is terrorized by a series of videotapes planted on their front porch.    

SIMPLE CONCEPT BUT REQUIRES SOME EFFORT.   EFFORT REWARDED BY THE LAST FRAMES WHICH WILL LEAVE YOU SPINNING, GUARANTEED.  I  RECOMMEND A READ OF [THIS*] ONCE YOU'RE DONE TO ASSIST DIGESTION... (*spoilers)

I RECENTLY FOUND OUT THAT FOR BETTER OR WORSE, MARTIN SCORSESE WILL BE DOING A HOLLYWOOD REMAKE STARING LEONARDO DICAPRIO, SO I'LL BE VERY INTERESTED TO WATCH HIS REINTERPRETATION SOON...
