Mr. Day-Lewis is particularly outstanding as a man out of time and out of touch. His gaunt face (he lost several pounds for the role) registers the anxiety and futile determination of someone slowly imploding. He makes the whole thing worthwhile.
When Daniel Day-Lewis sprays lead in his new film, though, we're supposed to consider him a misunderstood romantic, a crusading outlaw. Bob Dylan keeps popping up on the soundtrack to make sure you get the point.
