The reviews here that say the movie is too long (or "too long for a 1930s musical") must be written by people from fleet street. The movie is as long as it needs to be for a nicely complex storyline, nicely told with lots and lots of beautiful music to entertain, and Jeanette even gets a lot of dancing and wonderful non-dance choreography through crowds of men that she tantalizes with her charm.
The love scenes between MacDonald and Jones are funny, sweet, captivating, and the necessary betrayals are handled well and understandably from both sides.
I loved every minute of this film and would not have wanted it shortened. All the songs are hummable and lively/romantic. MacDonald's intelligence and sense of humor underlie everything she does, as when she says to Jones after his beautifully sung love song, "Well, perhaps I shouldn't tell you this, but you know that part where you sing, 'My heart's your throne dear, my heart's your throne dear, There you shall rule alone...' with the music building just before the high note?"
"Yes?"
"I was wondering... but, no, perhaps I shouldn't tell you."
"Tell me."
"Well, I was wondering ... if you were going to make it."
Or when Jones complains to her, "You're always saying goodbye," and she replies, "All right then, I won't say goodbye. I'll just ... go."
Her comic timing is lovely.
In fact, she has never been lovelier than in this movie, and the two of them together are just a lot of doggone fun and romance.
