When I first saw this film, the most striking thing to me was the convincing worldbuilding. Every alien species they showcase maintains enough traits similar to animals we recognize, that you get this sense they could be real, but is just outlandish enough to where you know it could only exist on another planet. Particularly there is this birdlike animal with a suction mouth for eating inside of logs. Just close enough to what we know to be understood, but just foreign enough to be compelling.
