One thing I feel people don’t talk about that make movies like obsession really good is knowing how to pace the escalation of stakes. The car scene is a dime a dozen in horror movies but is the biggest drastic event so far at that point in the movie
And even tho the scene is so predictable with how it’s set up, it still hits hard cuz its a tipping point that’s gone too far based on what we’ve already seen. Death wasn’t a threat until now
