The suspense, which runs the entire length of the movie, is a bit hard to bear. The movie also feels incomplete, some stuff left unexplained:

  • why is the robot sinister
  • why does the robot help near the end
  • what's up with the old man
  • ...

The creature design of the humanoid creatures is incredible. The ending is solid, and the famous alien, which is in baby form, is flawless.
