That movie made me angry. Angry at the world, at Ben Gazzara, Marco Ferreri, Italians in general, and angry at my VCR (this was some time ago). I didn't want to touch the tape after it ended, so I just unplugged the VCR and threw it out the window.
That just begins to explain how horrible that movie is. It's only the tip of the iceberg, really.
Imagine someone aggressively jamming a screwdriver way up your nose, until it hits important stuff, and they sit in front of you and do that repeatedly for an hour and a half. That's kind of like the experience of watching this movie.
But the screwdriver may be a bit more enjoyable (since after a few pokes, the screwdriver would probably render you senseless, so the rest of the 90 minutes would pass relatively peacefully).
Enjoy!
