I thought I had seen some really mentally disturbed & tasteless movies in The Voices (2014) and Jo-Jo Rabbit (2019)
But this one really has to be it. I think a living dead fart-powered man with a direction-finding boner beats even a serial killer comedy with wacky arguments with victims' heads, and a lovable Adolf Hitler.
Strange times we live in. These movies themselves do not shock or upset me. It's more the fact that we live in a society where they are considered viable entertainment.
Seriously, read the plot summary on Wikipedia. At any time prior to the 2010s this script would have been considered ridiculous and thrown in the trash. The writers must have shaken their heads in astonishment when it was accepted. I am sure they submitted it as a prank.
