The premise is preposterous, the character’s motivations nonsensical, and the gaps in the plot are the size of potholes, but if you can turn your brain off for a couple of hours, the movie is an enjoyable ride. Tom Hanks mails in a lackluster performance, and the girl is unmemorable, but Ewan McGregor is good, and Armin Mueller-Stahl and Stellan Skarsgaard shine in smaller roles. The road chases between famous Roman landmarks are fun, even if the Vatican scenes are all CG. The Catholic Church is no fan of this movie, which indeed takes a very anti-Catholic tone. But at the end, the portrayal of the modern papacy, and the Church itself, is surprisingly positive. Go figure.
