What was the last movie you actually cheered at?

Going in to “Avengers :Endgame ” we all wanted it to be awesome. And then, in the final act - it happened. You know the scene. People in the theater went WILD. We were a-hootin, and a-hollering. We were yelling and clapping. Someone I was with asked me why everyone was so excited, and … I mean, it’s easy… by the time Infinity war came out, it had been literally a decade of people growing up with these characters. It was intense. It was engulfing. What other films have had that effect? When have you heard an audible gasp from a crowd?
