Maybe my opinion’s void as I lack the stomach to sit through any films in this franchise, but I think you’ve nailed it.
From what friends have told me and what I’ve gathered from synopses and play-by-play’s on Wikipedia and content guides (call it my refusal to take having the privilege to not sit through these films for granted), the original films drew inspiration from a disturbing-but-thought-provoking game of Would You Rather meets Rube Goldberg. Now it’s Final Destination if an engineer sat in for the Grim Reaper.
When movies get the carnage turns from action-violence aftermath to intentional viscera, I’m the first to turn away, but if they can somehow justify it, that puts it a notch above torture porn. However, acting like you’ve justified it when you haven’t should clock you in at a notch or two below.
