"Wacky Blackout" is a Looney Tunes cartoon that is rarely seen today....and for some reason it's posted along with many other cartoons on HBO Max. Its rarity is because the cartoon is clearly a propaganda picture and has tons of references to WWII....so many that most viewers today would feel lost. Additionally, and most importantly, the short just isn't funny nor is there much to recommend it. It also looks nothing like a Looney Tunes short...with lifelike characters and the animation looks like it was done by entirely different artists. Perhaps the best artists were working for the government and the war effort and we are seeing the 'second string' unit here!
By the way, if you care, the "I Dood It" that is repeated often by one of the characters is a takeoff on Red Skelton and his catch phrase.
