It was a big flying predator from space, like a floating shelled sea creature with gooey parts inside. It wanted easy access to food like any wild animal hence all the theming and exposition about understanding wild creatures but not projecting human emotions onto them that aren’t there.

Why would anything more be explained when our characters were not given more? We aren’t suppose to know everything about the creature because how could we without an alien David Attenborough narrating all that stuff and ruining the mystery?

I don’t consider it a horror movie, more like those thriller alien encounter films that seemed more prevalent in the 80s. It had a handful of horrifying parts but it’s kind of a mystery / action movie with long periods of buildup.

It’s okay if you didn’t like it, I dont think it needed more explanation tho.
