Half-brilliant (the first half). Half-baked (the second half). You put up with the second half because the first half is so wonderful, and the ending is your reward.
Why do Barbara Stanwyck’s character and Henry Fonda’s character fall in love? Well, there’s the sexual chemistry. Even in black and white, and in spite of the Hays code, the frisson between these two fine actors is impossible to miss.
Jean has Hopsy exactly where she wants him. Then she realizes she really does want him. For all his innocence, there’s something, well, manly about the dear boy. But it takes him an awfully long time to realize that he wants her, too. Not his fantasy of her, but the clever, flawed, and vulnerable woman she is. He loves her complexity.
I think the second half of the movie is disappointing because Stanwyck’s character is not herself. She’s playing a shallow aristocrat and you forget how conflicted she is. Slapstick takes over at this point; Fonda’s character falls for Stanwyck, but literally this time. Over and over. It’s tiresome.
Only in the final minutes does Stanwyck regain her edge.
Her victory is fleeting because, darn it, she still loves the guy and can’t bring herself to take advantage of him. Wouldn’t you know it, though? Good old Hopsy comes around, realizes what he’s got, and lets Stanwyck win him back.
