Niko_Ramses’s review published on Letterboxd:
From each carefully plotted line of dialogue that recontextualizes everything that came before it, to the cinematography that consists mostly of medium and medium-close shots which elevate the unsettling claustrophobic feeling that Kaufman excellently captures, not one detail of the film can be dismissed as purposeless. And despite this being my first time watching I'm Thinking of Ending Things, I’m certain that it’s an experience that would only be enhanced by further viewings.
While the film is deliberately slow-paced and meditative in its nature, I find that the runtime was perhaps 20 minutes too long. I’m Thinking of Ending Things certainly is not for everyone and this long and drawn-out structure of story would definitely be the straw that breaks the camel’s back for most people. But that's not to say that I didn't enjoy those 20 minutes. In fact, there was not a single moment where I was less captivated than before.
What I believe I’m Thinking of Ending Things does so well is its ability to capture the fragility of time through various scenes of longing and regret (as demonstrated in the scenes with Jake’s parents, the couple in the car and the janitor in the high school) that culminate in an overwhelming feeling of dread. Perhaps the hardest part of living is being alive. Kaufman asks audiences the question, should one move forward, or should one stay still as time passes them by? To quote the anthropomorphic clock that gave me an existential crisis, “Time is a tool to put on the wall, or wear it on your wrist. The past is far behind us, the future doesn’t exist.”
