Surely everyone likes "good" movies, it's just highly subjective what that means. I agree that Signs is similar in that it doesn't explain a ton about the alien. But it's also way more obsessed with telling a story clearly than breaking from film conventions and focusing more on the allegory. I think Us did this too, but imo Nope was more successful in how it did it.

What i'm trying to get at is, and i'm just curious, are there any movies you like that don't explain their plot entirely? Neon Genesis? Tree of Life? Even Perfect Blue gets pretty out there.
