Upon its release in **May 1931**, Fritz Lang’s *M* was a major commercial success but faced a deeply polarized critical reception. While the public was captivated, critics were divided between praising its technical innovation and condemning its "sensationalist" subject matter.
### **1. Initial German Reception (May 1931)**
The film premiered at the **UFA-Palast am Zoo** in Berlin on May 11, 1931.
* **Audience Reaction:** Audiences were overwhelmingly enthusiastic. Despite the grim subject matter, the film was one of the biggest box-office hits of the late Weimar Republic.
* **The "Sensationalism" Critique:** Because the film followed so closely on the heels of the real-life trial and execution of **Peter Kürten** (the "Vampire of Düsseldorf"), some critics accused Lang of exploitation.
* **Gabriele Tergit**, a prominent journalist for *Die Weltbühne*, panned the film as **"headline-chasing sensationalism"** and **"filmed sadism."** She famously wrote, "The beast was just in court, and already on the screen!"
* **The Sympathy Controversy:** A significant point of contention was the final "kangaroo court" scene. Critics were unsettled by the way Lang and actor Peter Lorre made the child murderer, Hans Beckert, a pitiable figure. Some reviewers felt the film went too far in asking the audience to understand the "uncontrollable urges" of a monster.
### **2. Technical and Artistic Acclaim**
Despite the moral controversy, the German press widely recognized the film as a masterpiece of the new "talkie" era.
* **Innovative Sound:** Critics in major papers like the *Berliner Tageblatt* and *Film-Kurier* praised Lang’s use of sound. Unlike early Hollywood "talkies" that were dialogue-heavy, *M* was noted for its **creative silence** and the **whistling leitmotif** (Grieg’s "In the Hall of the Mountain King"), which served as the killer’s calling card.
* **Peter Lorre’s Performance:** This was Lorre’s breakthrough role. Reviews described his performance as "mesmerizing" and "haunting," though it immediately led to him being typecast as a villainous "outsider."
### **3. Political and Censorship Issues**
The film faced political hurdles even before its release:
* **The Title Change:** The original title was ***Mörder unter uns*** (*Murderers Among Us*). Lang famously claimed that the Nazi party, still rising to power at the time, denied him studio space at Staaken because they believed the title was a direct attack on them. After Lang clarified the plot was about a child killer, they relented, but the title was shortened to simply *M*.
* **Nazi Reaction:** Ironically, **Joseph Goebbels** (the future Nazi Propaganda Minister) initially praised the film as "fantastic" and "free of phony humanitarian sentiments." However, by 1934, the Nazi regime banned the film entirely.
### **4. International Reception (1932–1933)**
When the film reached the UK and USA, the reception shifted toward high-art prestige.
* **United States (1933):** Released in March 1933, the film received strong reviews. **Mordaunt Hall** of *The New York Times* called it "a clinical study of a diseased mind," praising its direction while noting it was "almost too horrible to witness."
* **The Nation:** Critic William Troy praised it for being more than a horror film, calling it a "psychological document" that transcended the simple sensationalism of earlier German expressionist films like *The Cabinet of Dr. Caligari*.
* **United Kingdom:** **Graham Greene**, writing for *The Spectator*, would later call it one of the most important films ever made, famously comparing Lang’s direction to looking through a microscope at a "tangled mind."
### **Summary of Key Criticisms at the Time:**
