There's a lot of stuff about appearance vs reality, and whether there is reality, which seemed important the first time but now comes across as pretentious rather than interesting. It made me think of The Society of The Spectacle, an anarchist/situationist pamphlet that appeared the year after the film, which also seemed to me to profound and important at one point, and now doesn't. There are some ghastly sex scenes with the implication of coercion (see the poster), and another scene in a London club that is both exploiting and poking fun at the tawdry glamour of the emerging rock scene.
Watched in the Middle Floor at Springhill Common House - I think from an actual DVD, which felt very old-school.
