It’s easy to be cynical about a movie like “Two Tickets to Greece.” Featuring two single, middle-age French women who travel together to the Greek isles, the just-released film contains all the clichés one would expect from such a set-up: gorgeous scenery, boat rides, flirtations with local men and fellow tourists, heart-to-heart conversations, rehashed resentments, reconciliations, and, of course, dancing.
