If I remember correctly, the old formula for the pacing of the Friday 13th films was that every 10 minutes:
1. Someone had to die.
2. Someone had to flash their boobs… and then die.
I’m not sure how much truth there is to this, as I’ve never sat down and actually timed it, but I’m inclined to believe it’s at least somewhat true.
Especially in the case of Jason X.
If anything, Jason X could be viewed as the overachiever of the series, as I seem to recall a few sequences in there where multiple character were killed off over the course of only a few minutes.
