I understand why you wonder. With the fervor of a recent convert, I can even find things to enjoy in Saw V, which objectively is not a creatively successful movie. (And I did believe how it ended. I was happy w/how it ended, but I believed it).
And I've seen the goriest of 'em (III) enough times I could use it as a lullaby.
So, I understand why you wonder. Does my love for the Saw series know any bounds?
...why yes, yes it does.
This is pointless...
