This easygoing rom-com is cute … but dumb.
Unlike its title character, who is cute and smart.
Granted, the result often is charming and goes down easily; there are worse ways to spend 105 minutes. Happy endings can be quite satisfying, even when they’re telegraphed from the onset.
Boston-based Anna (Deschanel) and Russ (Cox) share alternating custody weeks of their beloved dog, Merv (Gus), after having gone their separate ways. Their break-up — after several years together — came as surprise to friends and family, who believed them an ideal couple destined for marriage.
Russ works as an elementary school teacher, and has a good time with his young students. Alas, he’s a wreck at home: listless, unwilling to clean up stuff, clearly unhappy. Anna, an optometrist, is professional but stoic; she conceals her feelings to friends and colleagues.
Christmas is approaching, and — regardless of who he’s with — Merv is inconsolable. He mopes constantly and shows little interest in playing. A concerned visit to a vet (Andrea Laing) reveals nothing physically wrong, but she perceptively notices that Merv is depressed. Why? Because he likes having both of his people around.
Well, that isn’t in the cards (although we know it is, eventually). Meanwhile, Russ impulsively feigns the flu to get out of work, and bundles Merv up for a relaxing and playful week at a Florida-based doggy spa. This setting is laden with opportunities for sight gags, and Clark and Stewart don’t miss any: dogs doing yoga, an oh-so-sincere animal “spiritual healer” (Wynn Everett) and plenty of lunatic owners.
The dynamic gets even more chaotic when Anna crashes the party: not because she misses Russ (although she clearly does), but supposedly so Merv can benefit from a week with both of them.
Russ loves the beachified surroundings; Anna is (ahem) allergic to sunlight, which gives costume designer Allison Pearce an excuse to pour Deschanel into all sorts of unflattering outfits. Apparently that’s intended to be funny, but it comes off as weird.
