What movie feels impossible to watch without captions?

I was recently watching the Sixth Sense, which prompted me to wonder if I’m the only one that feels like some movies feel truly impossible to follow everything in the story without captions. For this movie specifically, Haley Joel Osment’s character was difficult to hear in his particular speech patterns and hushed voice.

I know Tenet is infamously not-great with it’s sound design that this could be another example.

What are some of yours? Tell me I’m not the only one.
