This movie isn't nearly as funny as it thinks it is...or even what it is heralded as.  I had a conversation with my fellow movie reviewer recently about these old movies and how sometimes...we just don't get the popularity.  I think a great movie is timeless...and there is no such thing as good for its time.  I can appreciate significance and historical relevance...but a bore is a bore is a bore.  Countless articles about The Lady Eve talk about how it is one of the comedy greats, and Barbara Stanwyck's performace is one of the best all time.  Nope.  The whole movie is man falls in love with woman.  Woman is a con artist.  Man falls in love with the woman again later when she shows up in a new personna and man believes it CAN'T be the same woman, because they look EXACTLY alike.  Meh.  Some parts are silly fun and I DO like how Stanwyck and Henry Fonda play off eachother...but a classic?  I don't buy it.
