Paddington 2.
The Paddington movies are so damn good, something both kids and adults can thoroughly enjoy. And it's an excellent example of great script writing, casting, pacing, building emotional stakes, setup / payoff and having character arcs.
On a recent flight I watched Philadelphia, towards the end when everyone is saying bye to Tom Hanks in the hospital got me hard. "I'll see you tomorrow buddy".
Haven't watched Eternal Sunshine of a Spotless Mind in a while, not sure how it holds up. But the last fight scene between Joe and Clementine always puts a lump in my throat.
And Marriage Story, Adam Driver and Scarlett Johansson are 100% on their monologues and argument scenes.
