September 2017 is Syfy’s 25th anniversary, so we’re using it as an excuse to look back and celebrate the last 25 years of ALL science fiction, fantasy, and horror, a time that has seen the genres we love conquer the world of pop culture. For us, that means lists! ALL THE LISTS! We’ll be doing two “25 greatest” lists per day all throughout September, looking back at the moments, people, and characters that shaped the last quarter century. So keep checking back. Please note: Our lists are not ranked; all items have equal standing in our brains.

What items in our lists were your favorites? Did we miss something? We welcome respectful debate and discussion, so please let us know in the comments!

Science fiction films are not just about spaceships, robots, and lasers. It does often contain those things, but that’s barely the tip of the space-berg. Sci-fi on a cinematic level can truly immerse audiences on a scale that is not always possible on television, but as is almost always the case, it’s the ideas and concepts that matter most. The best science fiction films use the joys of this heightened genre to reflect our own world right back at us, and inspire us in ways that we never thought possible. So beam on down, take a “Baby Diego” day, and write “human” on your whiteboards as we aim to misbehave with our list of the 25 greatest sci-fi films of the last 25 years.
