That was a great way of doing your list, Demdike, and similar to what I had in mind when I was describing the subject in my post.
There are different places and locations for different films, so I'd love to be in that first queue to watch
Psycho when no one knew the twist, something completely different from seeing something like
Zombie Flesh Eaters in a fleapit with a mix of bemused drug addicts and hardcore horror fans, being a young child in 1964 and being swept up in the magic of
Mary Poppins, or watching
Battleship Potemkin in 1925 Soviet cinema and being caught up in revolutionary fervour.
It will take a lot of thought!
