Few things are certain in this world, but as long as there's a hole in both ends of you, Hollywood will continue to make sequels like there's no tomorrow. After all, returning to the same well over and over guarantees an audience and means nobody has to spend years trying to develop original ideas that might end up being expensive failures.
Unfortunately, the major studios' perversion for sequels means that quite a few film franchises end up over-staying their welcome to the point that the announcements of new installments are more likely to elicit groans rather than excitement. Sometimes, these films have the good grace to disappear to VOD or straight to home release without bothering the multiplex, but even a cursory glance at the next couple of years' movie slate confirms that there are just as many sequels coming as ever.
It's not all soul-destroying though, because some of those projects - even the ones that absolutely nobody would have remotely asked for - might actually end up being great...
10. Saw IX
Strictly speaking, the forthcoming 2020 Saw movie is a little difficult to classify at this stage, with various outlets reporting it as a spin-off or a reboot or simply a new take in the same universe. None of these would be particularly exciting for the wider community, because the danger is just that everyone looks at the title and rolls their eyes. It's easy to dismiss new Saw movies, just as it is to dismiss Purge movies (there's another one of them too, and you'll hear about it soon) or any other gimmick-heavy horror franchise with multiple sequels.
But this is different: the big selling point here is that Chris Rock is the man behind the new film. He conceived the idea and handed it over to Pete Goldfinger and Josh Stolberg to write, while the original's creators James Wan and Leigh Whannell will executive produce, which suggests confidence at the very least.
Nobody would have asked for anything like this new take, but it's intriguing. Comedy actors have had great recent form with horrors thanks to Jordan Peele's Get Out and Us and Danny McBride writing the Halloween rebirth. There's no reason to think Rock can't give it a good go too.
