Pier Paolo Pasolini has with the Decameron what is supposedly one of his "happiest" movies. This is not to say the film is always cheery- matter of fact a couple of the stories deep down are pretty dark and sad and cursed thanks to the repression of religion and mortal sins- but Pasolini's comedy here is sharp and his wit comes out in the obscene or in the random. It's a little like Bunuel only with a more earthy sensibility with the locations and slightly less surreal situations; it doesn't mean that Pasolini is any less ambitious with treating the foibles and stringent ways of the Catholic Church.
The Decameron's only big liability, in my estimation, is that it could be easy to get lost in the structure Pasolini sets up; it's nine stories, ranging from a Sicillian being swindled after finding out he's a brother to a sister of royalty until he's covered in feces, to a supposedly deaf-mute boy who becomes the sex toy for a bunch of sex-starved nuns, to a supposed 'Saint' who fools a priest into thinking he's such with his lackluster confessional, to a girl being met by her boyfriend on the roof and then being (joyfully) caught by her parents since his family is wealthy. They're all interesting stories, more often than not, with even a really short piece like the priest attempting to seduce his friend's wife providing something amusing or eye-catching visually.
But, again, all of these stories go from one into the next without much warning, and one may wonder when the next story really begins or if it's a continuation of the last. As it turns out, like the Phantom of Liberty, it's very stream-of-consciousness and one skewering of morality and sex can bleed easily into the other. And yet some may find this to be a more daring strength than others; certainly it's a very funny movie (if not quite as funny as Pasolini's masterpiece The Hawks and the Sparrows), like with the bit of the guy caught in the tomb, to the frankness of the parents asking the boy to marry their daughter on the rooftop - even just the strange feeling one gets watching the painter (played by, I think, Pasolini himself) in the act of creating an unusual but unique work on a church wall.
The greatest thing of all, for fans of the subversive, is that nothing is out of bounds for Pasolini, via his source material of the Boccaccio book, and he never is one to ever shy away from sex. That's also another asset this time around- unlike Arabian Nights we get some actually erotic bits thrown in the midst, if unintentionally, and on occasion (i.e. the shot following Lorenzo as he runs by the fence) the director conjures something powerful amidst the medieval/surreal/neo-realist pastiche. 8.5/10
