Party 7 (2000)
When it comes to boundary-pushing off the wall cinema, Japan is the world's undisputed leader. Party 7 is one of the most bizarre, creative and hilarious films I've seen in a very long time. Set almost entirely in a hotel room with adjoining peep-suite, the film thrusts together an ensemble of quirky characters and feeds them a non-stop supply of bizarre, perverse and highly amusing dialogue. The plot is almost non-existent, yet manages to be clever and surprising, and the delivery is perfect. You haven't seen anything like it, and you're either going to love it or hate it... it's as simple as that.
Me, I loved every little bit of it!
