honestly i struggle to even call it fantasy, to me it just feels like a normal-ass movie with whatever justifications they needed to make things happen
like how back to the future isn't scifi or fantasy either, it's just a movie about going back in time and how they do that is entirely arbitrary and exists only to justify time travel and to be cool.
there really should be 2, though. a proper impact-absorbing guardrail between the road and the sidewalk, and a normal railing on the edge of the sidewalk.
