The “Alien” movies vary widely in quality — there arguably hasn’t been a truly satisfying one since the first two in 1979 and 1986 — but a key thread has endured across the 46 years: However scary the xenomorphs are, “Alien” has always feared AI and the greed of faceless corporations. And in that respect, its time has come.

The latest entry in the franchise, “Alien: Earth,” which premieres on Tuesday, certainly exhibits those political undercurrents while bringing the threat home, both in the location and the shift from theaters to FX and Hulu, where only your neighbors can hear you scream.
