Jamie Brightmore’s “cinematic journey” around Banksy’s Dismaland is the best thing I’ve seen covering the pop-up theme park in England. The details, lost and glossed over in heavily-narrated news coverage, are here to be experienced up close.

The venue, a derelict outdoor swimming pool, now returns to its more mundane dismality.
