It has nostalgia value, too, like those 60s thrillers with Cary Grant and Audsrey Hepburn running around Europe accused of a crime he didn't commit, running from people without knowing why. American innocence confronting European horror.
BTW Ron Howard did a good directing job. And Tom Hanks is just fine, as is Mlle. Tatou and the supporting cast. Ian McKellen steals the show with his good-guy/bad-guy/who knows what? English lord star turn.
Favorite line: "I've got to get to a library!"
Not to be taken seriously. But a lot of fun. Plus, I love the cinematic references to "A Beautiful Mind" in the puzzle-solving scenes when Tom Hanks sees glowing letters and swirling orbs. The protagonist of that earlier Ron Howard/Akiva Goldsman film--as all you Harvard symbology professors reading this surely know--was a paranoid schizophrenic.
