Greenaway has more than once been known to disappear up his own aesthetics, but this collection of his short films plays to his strengths, tolerating little tedium. Disc One includes six films exploring his constant themes, from A Walk Through H (numbers, maps, the afterlife) to Windows (37 people fall through windows to their deaths). Disc Two features the obsessive Vertical Features Remake and The Falls (92 mini-biogs), and is?if you’re in the mood?monumental like video art pioneer Bill Viola.
