Christopher Nolan's The Odyssey is the most spectacular film of the summer and leaves you slightly, inexplicably unmoved, which is the exact and only problem with it. Matt Damon as a crushed, grizzled Odysseus is inspired. Samantha Morton's Circe is extraordinary. The cyclops sequence is one of the year's best setpieces. We talk about why Nolan's structural genius and the emotional demands of Homer's homecoming don't quite meet, and whether any of that matters when you're watching it in IMAX.
