THE TENANT is a brilliant film, and like some of Polanski’s other films like REPULSION or KNIFE IN THE WATER, one can glean its influence (in films like IMAGES or DEAD CALM, for example). I feel like there’s a lot of THE TENANT in much of Michael Haneke’s work.
But never really sought out the score. I remember it as too abstract for my delicate sensibilities. Maybe things have changed; should give it another go.
