So... I love morbid creeper type shit. I loved watching to catch a predator. I also like movies like falling down, and one hour photo. I just watched silence of the lambs for the first time and I like that too, soon ill get red dragon and hannibal. One movie ive yet to see that id like to see is "the fan" which is about a young man who romantically stalks this older woman who is a famous singer. Basically what I am looking for: A movie where you got a sick sick son of a bitch whose creeping around doing shady stuff had all kinds of nasty stuff hidden in his home and gets caught! I don't think anyone has made movies about nambla members getting busted but that would be awesome!!
'Hard candy' is just the movie for you. (Dont google it, just watch it...it will make it much better if you dont know to much about it) Also if you havnt seen( one hour photo )that fits most of your discription. Swimfan was a creepy stalker movie too.
