Vertigo

just like north by northwest, threwout the film it was an 8/10 but thinking about it, its such a good exploration about obsession and how it can make you a terrible person.
obsessions are dangerous, at least specific cases like being obsessed with guns. being obsessed with a person(like in this film)
but obsession also drives us, there is a reason allot of films only happen because of obsession even if the film isn't about it.
