It turns out that Jess Franco with lots and lots of money means a movie that looks great but is completely empty, inexplicably padded to run a frankly offensive 124 minutes, and big name stars either gleefully being parodies of themselves or just wandering in, sitting around for a bit, picking up a check, and leaving. (With both Jack Palance and Mercedes McCambridge in the cast, I think we can all guess who was doing what.)
In other words, Marquis de Sade's Justine is a completely waste of time, almost entirely without Franco's usual intensity, curiosity, and discomfort, all of which has been replaced by shiny things, a fucking HAPPY ENDING (!??!?!!), and periodic, faux philosophical lines that are stuck…
