It is crazy. I tried the same prompts and got nearly identical images to the author. AI seems to be repeating itself with the same images without variations.
I'm surprised by the comments here. When your prompt is so mind-numbingly simple, an obvious "dare" for AI to be a naughty little copyright infringer, can you blame it for dishing up the "big mac" you asked for while sitting in a fancy restaurant?
Don't want Indiana Jones? Don't ask for Indiana Jones!
