Yeah it’s a strange phenomenon isn’t it? I wondered that a few months ago watching Oppenheimer.What's weird is it seems like lots of current blockbusters are way more than 2 hours.
Many of these last few Star Wars, Superhero movies et al were quite a bit longer than a classic like Jaws and had a whole bunch of forgettable scenes.
You'd think it would be the opposite to grab the attention while people have it.
