Just watched Patrick Keiller's "London" (1994) on BFI player, I should think this film would be right up dissensian's streets if they've not seen it already
I didn't really know what I was getting into, thought it might just be interesting to see London as it looked 30 years ago, when there's a good chance I visited it once or twice, as a 7 year old (it's 'set in' 1992). And it was interesting on that level, plus to see how it's changed – the South Bank seemingly dormant or dead at that time.
But it's also contemporarily relevant in all sorts of dispiriting ways, there's a lengthy diatribe about what the re-election of the Tories means for the future of the city which could easily be transposed to 2023. (The video I posted above, in fact.)
Most of all it made me feel either ashamed or deprived to be so ignorant about the city in which I live and uninterested in learning more about it. Even though it closes by suggesting that Londoners can't 'know' London in any real sense, and that London is the most modern city because it 'doesn't exist' and was 'the first metropolis to disappear'.
Found some bits a little pretentious, esp. with the repteitive use of Beethoven's late string quartets but on the whole a real surprise and I loved it.
