Caligula was reviled by film critics even before it hit the screen. It had a checked production history. Here's a representative review by Roger Ebert:
Ebert was an atheist. A lapsed Catholic. Very worldly. Had no problem with X-rated movies or heavy-duty violence. Yet despite all that, he and other equally worldly film critics were morally repelled by the film.
Why do I bring it up? Because, as I read this old review, it's my impression that a lot of current film fare and HBO fare has the same content that film critics a generation ago found too abhorrent even for their jaded tastes. The coarsening of the general culture is far advanced.
