The Worst Sci-Fi Sequel of All Time

Sci-fi franchises soar when fresh ideas meet strong worldbuilding, but sequels don’t always stick the landing. This list looks back at follow-ups that changed tone, swapped creative teams, or leaned into risky pivots that fans still talk about. You’ll find studio shakeups, cast overhauls, and production constraints that shaped what ended up on screen. From retooling mythologies to stretching budgets thin, these entries show how tricky it is to continue a hit. Here’s a snapshot of what each film actually did, who made it, and how it fits into its series timeline.
