2020 was a messed up year, but it managed to bring us some good films, and the UK's Independent says I'm Thinking of Ending Things is up there in the top 10. #6, if you want specifics.
6. I’m Thinking of Ending Things
Writer-director Charlie Kaufman, once enough of an idealist to give his lovers in Eternal Sunshine of the Spotless Mind a second shot, has curdled in the intervening years. I’m Thinking of Ending Things is arguably his bleakest film – it’s also one of his best. “I’m thinking of ending things,” a young woman (Jessie Buckley) says to herself. She chews over the words, repeating them over and over again in the hope that they’ll suddenly gain the significance she was searching for.
She’s not quite sure what she wants to end. Is it her life? Her relationship with Jake (Jesse Plemons)? They’re on their first substantial trip together – a visit to his parents, out on their farm. But details start to change without warning: clothes, jobs and hobbies. Jake’s parents (Toni Colette and David Thewlis) age rapidly between scenes, as if we’re watching corpses decompose before our eyes. Kaufman has taken Ian Reid’s debut novel, published in 2016, and replaced its bait-and-switch ending with a single mood – one that’s not so much about suicidal ideation or break-ups as the black hole of emotions they have a tendency to create. Suddenly, I’m Thinking of Ending Things starts to feel like the most frightening film of the year. (Source)
