After Titane, this is further proof that the Palm D' Or doesn't amount to much nowadays. First hour is okay but the lame rhetorics gradually take over, as if the director was trying very hard to disguise that he is making a message movie, but then decides to hit you hard with lousy slogans and quotes in case you have noticed that rich people are a bunch of privileged assholes. He then demonstrates that despite being rich, they're all full of shit, just like the rest of us.
After the pirates show up, the whole thing falls apart. It's cheap, with a disjointed narrative that makes little sense, leading to the most stupid ending you can imagine. But worst of all are the two-dimensional characters, more stereotypical than any Hollywood film. They are poorly developed and unlikeable. Not knowing what to do with them, the writers resort to laughable gimmicks like the "Robinson Crusoe" section on the island-an inhabited island keep in mind- which makes the idea even more stupid.
Last two minutes will make you want to punch the director in the face - especially if you bought a ticket to see this thing. The fact that this is supposed to be an "art" film doesn't mean that it shouldn't have a proper ending.
To summarize everything : Art film equals lots of puke (a poor shock gimmick probably lifted off a Mae Zetterling film) and lots of shit (exploding toilets) and bored rich people.
If you don't get it, you got to be an idiot!
