Sounds like a movie that is trying to normalize reptilians.
I know about the Japanese guy. But if the movie is truly subversive, would it get an Oscar? Think about it. We are invited to like an alien creature (reptilian, amphibian, no matter) under the pretense of this being a subversive idea.
This creature looks demonic. What are we asked to do? To over-write our natural impulses.
Starting with ET (at least) they have been programming us to miscegenate with other species. Why? Think about it. Love is exactly the opposite. Love is the force that maintains order, complexity, and natural affinities, not chaos and confusion.
