I see what you're saying, but I would argue that story construction is typically one of the least original parts of most movies. How many films are about a hero's girlfriend getting kidnapped so  he has to assault the villain's compound, face off with the villain, and rescue her at the end? That's like 20% of all movies, and there's lots of good ones in there.

Story structure is about using the best layout to tell the story you're trying to tell, and for this kind of story, I'd say this was the best way of structuring it.

The hard part of writing is the details, and it's the weird details and connections this movie chooses that make it so unique.
