It's not a masterpiece, but I actually found this film very enjoyable. It was a very interesting and inspiring look at feminism in the early 20th century, and was effective in its message.
Is it a thrilling and captivating suspense and drama film? Yes. Does Fritz Lang direct brilliantly and does Peter Lorre give his very best performance? Yes. Is it one of the most influential and groundbreaking films ever made? Yes. This is one of the most perfect films ever, and it is a highlight of the German Expressionist movement. It deals with insanity and murder better than perhaps any film in history, and exhibits a great amount of artistic expertise.
