It's a little cliched -- another uptight wife? -- and a little sitcom-y, but fine, witty writing and appealing actors go a long way to making this dour comedy more of a draw. It's annoying to watch Garner, so naturally sweet on camera, reduced to a binder-toting Type A pain with a burgeoning Instagram account (mostly for chronic pain sufferers and working moms), and Tennant as a henpecked husband, but the promises of both halves of the couple breaking down under wilderness stress is part of the charm of Camping.
Meanwhile, Lewis is a sheer delight as the uninhibited imp who unravels all of Kathryn's careful plans. She makes an enemy of Kathryn on the very first morning of the trip, listing off all her jobs back in L.A.: DJ, reiki healer, a maker of nuts and cheeses, she models for a figure-drawing class, and -- last but not least -- she's a notary. She met her most recent squeeze, Miguel, at a rave at her loft when he passed out on the Casper mattress she'd just "unfurled." She's a stereotype, the rough-around-the-edges la-la land free spirit, but the way Lewis throws herself into the role, she's the kind of kooky character audiences want to stick around for. This trip may not be going as planned, but the worse it goes, the more fun it is to watch.
