Well, I'm going to ignore the criticism out of Cannes (who incidentally turned down BBM last year - no accounting for taste) as the movie was filmed in Paris and France and they are French. Go figure.
Ebert liked it, apparently.
Anywho, the book wasn't that good to begin with, so the movie needed a lot stronger and more consistent director than Ron Howard ('A Beautiful Mind' versus 'Backdraft') as Ron can get schmaltzy and melodramatic.
However, the issue at the heart of the book is what I'm going for, it's certainly not for any 'chemistry' between the two stars which I gave up on the second I heard Tom Hanks was cast.
Tom Hanks + mullet = the "Indiana Jones" of cryptography?
What were they smokin'?
