The outstanding fact is that M-G-M has turned out an interesting dissertation on a thoroughly provocative subject. Jean Harlow, hitherto not highly esteemed as an actress, gives an electric performance.Ethics of the subject are sufficient to make a church deacon gulp and stammer. Heroine (Harlow) is a home wrecker, a vicious vamp and a destroyer of peace, and the wages of sin in her case are paid in the final close-up in strange and wonderful coin. Picture is handled with a curious blending of bluntness and subtlety. Some of the ‘vamping’ sequences, and there are plenty of them, are torrid. But the overall effect is conveyed with a great deal of fancy skating over very thin ice and its very candor is disarming.
