My favorite is much darker, its a Spanish film called in a glass cage. It centers on a German scientist who tested poisons on camp prisoners. He was dispassionate about his work till one day a test subject didn't die right away, he was fascinated by his death rattle, and from then on he was hooked on their suffering. After the war he moved to Spain where he interacted with countless village boys. One day he is working over a yng victim and he has a heart attack and falls off a balcony. Unseen by the Dr a late teen was spying on him, apparently one of his former abused boys. This boy cleans up the evidence, takes the Dr to the hospital, an finds the drs journal/diary of every act he committed... Including the 20 yr old boy from when he was much younger. The Drs injuries are so debilitating that he requires a iron lung to survive. The Dr has a col nasty wife and a sweet cute preteen girl, but the Dr needs a caretaker.I hate movies like Harry Potter and Lord of the Rings.
Tried to watch them but failed.
I like dark, realistic movies like Taxi Driver which is among one of my favourites.
Any time you watch it you can find something new.
