For Sight & Sound I wrote about the Encounters Short Film and Animation Festival, which this year clocked up its twentieth anniversary. A lot of the event was in a retrospective mood; and quite a bit of the rest was occupied by something other than a film programme. If there’s a price to be paid as festivals transition gracefully over towards trade conferences under the magnetic pull of their own industry programmes, it’ll be the general audience that pays it. But the strand devoted to radical film-making found a rich vein to tap; up with this sort of thing.
