Tomei rediscovers her My Cousin Vinny sparkle as Ruby Weaver, a therapist-dependent New Yorker who, after years of frustrated dating, falls in love with a sweet, mellow Midwesterner. Turns out Ruby really is unlucky in love: Sam Deed (a charmingly stiff D’Onofrio) is, in fact, a time traveler from the year 2470. Will she go back to single life — or keep seeing Mr. Tomorrow? Forget the sometimes jarring shifts in plot: Writer-director Brad Anderson’s look at ultramodern romance will entertain even the most earthbound of skeptics.
