Werner Herzog coaxes stories from the least likely of places in this grisly death row documentary filled with operatic levels of tragedy – and unexpected humourAs Werner Herzog admitted, introducing his new documentary in Toronto, Into the Abyss is, for him, a fairly generic title. All his films are trips into the dark, from the most famous to the most recent: Cave of Forgotten Dreams , a woozy 3D tour around the paintings and scratchings at Chauvet with a trademark wacky coda featuring baby albino alligators.But rarely has a quest into the depths felt quite as larky as this one: a death row documentary that's, if not quite laugh a minute, then certainly not short on chuckles.
