These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Moment Of Awesome: Spade's one upping of the villains. The guy always keeps his cool.
Also, when Spade quickly and easily disarms the hotheaded gunman, Wilmer, taking his pistols. He later ridicules Wilmer about it, claiming that "A crippled newsie took them from him. I made him give them back."
Unintentionally Sympathetic: Joel Cairo, whose effeminate actions were supposed to creep out a 1940s audience but these days it just labels him as an outsider.
The fact that the 1941 film is set during a time when homosexuals were being murdered by the Nazis, and Cairo is clearly a foreigner with an Eastern European accent, makes him even more sympathetic.
