If you want to know what "intense" truly means, then, by all means, do subject yourself to this painful ordeal and when the runtime clock hits the 1h08m mark, keep. Your Eyes. On Jason.

To save you the trouble: Yes, there is no need to judge me for wasting my life reviewing this crap on top of watching it, to begin with. I judge myself aplenty.
