Forrest Gump makes me cry on and off throughout even though I've seen it 7965422 times, the last time I watched it was on a long haul flight last year having been up since 3am I was an emotional wreck
Avengers Endgame
Every damn time Woody says "So long, partner." at the end of Toy Story 3 I'm in tears. Every time.
The end of Inside Out.
And Onward also made me cry, I was hiding the tears from my friend in the cinema
Basically most Pixar films
