10 Most Disappointing Action Movie Sequels Ever

10. Robocop 3

Paul Verhoeven's Robocop remains one of the definitive action movies of the 1980s, as well as one of the decade's greats. While the inevitable sequel wasn't an awful follow-up, but a fairly derivative and uninspired one that couldn't hold a candle to the first installment, Robocop 3 flat-out sucks.

The writing should have been on the wall when Peter Weller decided against returning to his career-defining role, and the studio was so eager to keep the brand going that they didn't even bother making a new costume for his replacement Robert John Burke, despite the fact he was much taller than his predecessor.

The first Robocop was all about skewering consumerism, and nobody seemed to realize the irony in making the character's third outing PG-13 in order to increase its chances of box office success and appeal to a younger demographic.

Despite being made available to a wider audience, nobody really cared anyway as Robocop 3 was savaged by critics and tanked at the box office, marking a huge comedown for a franchise that had gotten off to an all-timer of a start just six years earlier.
