Polygon has picked out six science-fiction films worth watching on the horror-focused streaming service Shudder, aimed at horror fans willing to embrace cult and low-budget fare alongside occasional classics. The list highlights that Shudder's sci-fi catalogue is relatively small, at around 35 titles, and leans towards obscure, cheaply made or imported films rather than mainstream hits.

– Phantasm (1979, dir. Don Coscarelli): the original film in a franchise that later declined in quality; follows a mortician wielding alien technology and the boy investigating him, recommended as a tribute to the late Reggie Bannister
– Mosquito (1994, dir. Gary Jones): a low-budget creature feature about alien blood turning mosquitoes into giant killers, praised for its relentless pace and featuring Gunnar Hansen (the original Leatherface) and Stooges guitarist Ron Asheton
– Psycho Goreman (2020, dir. Steven Kostanski): described as a modern cult classic, though details are cut off in the provided text
– Three further titles are included in the full list but are not detailed in the available article text
