Collider has published a ranked list of the ten greatest science-fiction movie trilogies, compiled by senior writer Ryan Heffernan and released on 23 July 2026. The piece argues that sci-fi's blend of high-concept ideas, visual imagination and technical ambition has made it especially fertile ground for successful multi-film series, with most of the standout trilogies emerging from the blockbuster era of the 1970s-80s through to today's franchise-driven industry.

The supplied excerpt covers the two lowest-ranked entries. At number ten is the RoboCop trilogy (1987-1993), praised for Paul Verhoeven's satirical, action-driven original film but criticised for weaker sequels that diluted its tone. At number nine sits the Men in Black trilogy (1997-2012), though the article's discussion of it is cut off before further detail is given; the remaining eight entries on the list are not included in the available text.
