I can talk about some blockbusters. I like the Marvel's MCU movies (though each one progressively less, my favorite still being Iron Man 1). For me, they have a near-optimal composition of plot cadence, special effects, music and cliches. They're usually pretty polished. I find them good for light enjoyment, and since they also appeal to a very wide audience, it's something I'll immediately get to talk about with a lot of people, or something I can watch with my SO without worrying it'll bore her out of her mind.

It's fast food of entertainment. A composition optimized to appeal to senses, even though it's of questionable nutritional value. I think it's fine from time to time.
