Well, it's got one great character; pity that a great romantic comedy requires two. Hepburn radiates such wit and energy that she runs circles around Tracy, who spends most of the time glowering. The issues at play remain important—this is the same battle to "have it all" that, say, Tina Fey would be fighting 60 years later. But look at the studio-mandated ending, and celebrate that the terms of warfare have changed.
There is possibly the strongest female character of cinema and Stevens' movies still beyond its' time. Like Penny Serenade and The Talk of the Town. "How to survive your marriage" guide for newbies. Hepburn always plays strong and independent woman but Tracy wins at the end of the day. That's the rule.
70 years later, the main theme is still relevant. Academy award in the Best Writing, Original Screenplay. Furthermore, Woman of the Year conduces to dsicover the whole Katharine Hepburn filmography. Highly recommended.
