And the dialog in the game didn't?
"What is a wheelchair doing here??"
(not, "what are all these dead and mutilated half-human monsters doing here?")
Radio.
What's going on with that radio?
Yeah, the first game's dialog was pretty rough (what the hell is gyromancy?) but I don't think it was that bad for its time. The sequels got WAY better after all.
I've heard complaints about how the storyline was "all explained in a neat bundle of exposition" but I thought that a lot of the stuff, like good old Pyramid Head, was still just as weird and unexplained as it needed to be.
Still the best video game movie ever.
