I’m old enough to remember when movie theaters would have an “A” and “B” movie, and change them up on Wednesdays (unless they were “held over”. (and yes, I even recall the Saturday matinee marathons for us kiddies).
So many of the “A” movies (then and now) strike me as bloated bores (with, of course, many notable exceptions) But those “B” and “Z” grade movies have more re-watchability for sure.
Corman’s movies were at their best at drive ins, where nuance and refinement were unnecessary and the best action to be had was off screen.
