Although the acting is very good in "Ladies' Man", the film has one huge strike against it....you don't care very much for the main character. In some stories, this doesn't matter but for a romance, that's a significant problem!
Jamie (William Powell) is a gigolo who is romancing BOTH a woman (Carole Lombard) AND her mother at the same time! Now that really takes nerve! But what takes even more nerve is his beginning to date a third person (Kay Francis) at the same time! The daughter (Lombard) is pretty unstable and you can't help but think bad things will come of all this.
As I already said, the acting is very good and the story isn't bad. But you can't help but not care very much about Jamie or his exploits, as this guy uses women and has no interest in working and having a real job. Enjoying the high life off of women is his only goal in life....though meeting Norma (Francis) shakes his resolve. Watchable and interesting but no more.
