A last blog post in honour of Venice 2010 and I'm going to use it to tackle a topic that niggles close to my heart, like a partially-clogged pulmonary vein. It is not something specific to the Venice Film Festival by any means, but a couple of incidents at this year's event saw it brusquely stamp its way to the forefront of my thoughts, appropriately enough, given that a basic rudeness is key to this subject.
