From the moment it was announced, Alien: Earth was a bold punt. So the thought of subjecting it to an entire television series – one designed to run for several years, no less – risked destroying it completely. And yet Alien: Earth is a wild success. We should cross our fingers and hope that the finale is the Alien franchise’s Kramer vs Kramer moment. A long-form television series cannot be sustained by the angry toddler histrionics of a xenomorph.
