Woody Allen’s Vicky Cristina Barcelona (B+) is the latest in the writer/director’s European travelogue in which a Spaniard (Javier Bardem) proposes a three-way to two lovely travelers (Rebecca Hall and Scarlett Johansson), and then they all encounter his former wife (Penélope Cruz). Alternately ambiguous and enchanting, the film is full of comedy and rich characters, with everyone at the top of their game.
