But a Buck Rogers reboot wouldn't be set in the '30s, it would be set in the 25th century just like the original serials and the '80s version. What's being talked about is not setting it in the '30s but making it using a '30 aesthetic sort of resembling the old serials.
I could see a 1930s aesthetic working if they skip the sepia-toned look of the trailer. Give me color.
That 'Sky Captain and the World of Tomorrow' movie had a cool production design on the vehicles & costumes & stuff. But the filmmakers killed it with the extreme visual tone. Nobody wants to stare a flashlight pointing at their face for 2 hours.
