After intriguing buzz and a ton of secrecy, Alien: Earth has finally arrived. If there was any question that the Alien world wouldn’t work on TV, the terror of Alien: Earth proves otherwise. Because the show is called Alien: Earth, we’re made to understand that our characters have to have run-ins with aliens on Earth. But, arguably, the best aspects of Alien: Earth work totally independently of that preexisting aesthetic. Alien: Earth has seven more episodes to fully reveal what kind of sci-fi show it will evolve into.
