Essentially watched all the Saw movies from I to X here >>52287
Right now Spiral: From the Book of Saw is rolling, about halfway through. Was published in 2021 and it is as woke as it legs. A female Jigsaw imitator is killing corrupt cops. Chris Rock is the main PoC hero. If I disregard this, and consider only the classic Saw themes, it's still an awful movie and the lowest point.
If we step back to Jigsaw (2017), that's like a fanfiction.
Saw X is a step up from these, for sure, and more like in the veins of the "classic" ones.
The best, ofc, is the starting movie. It has gore, but has psychological element to it, and the final twist just crowns the whole thing.
Then as the series go on, the next few movies enriches the lore by adding the stories of other participants.
It is a good series, no wonder they made so many.
And they are in the making of the next one Saw XI. Planned by 2025.
