Peeping Tom

while peeping tom can linger to much on some of its scenes, its an excellent horror film.

Karlheinz Böhm gives a creepily and freightening good performance that makes him slightly sympathethic despite his actions.
it also helps that the colors POP like a horror comic, the cinematography is obviously beautifull but everything feels so colorfull but the lighting makes those colors sometimes seem normal and sometimes creepy.
