'Left Turn Thriller'

I call it that because it's one of those rare movies that, it seems like it's all set up to go some fairly standard direction, then out of nowhere comes a plot twist that you really had NO expectation of, and the movie takes a sudden left turn into unexpected territory: "You thought we were headed THAT way!!? Silly movie watcher, where we're going, we don't need... 'roads'!".

It is GOOD writing, in that the plot twist isn't wrong for the characters, but the evidence leading to it isn't obvious during the first part of the film.

You THINK you see where it's going, and then WHAM! it hits you in a sudden left turn out of nowhere.

In this movie's case, the moment happens almost exactly 45 minutes into it, when Harry breaks into Miles' apartment, and Miles calls HIM there... and says "Go *beep* Yourself".

Before this it looked as though Harry had all the cards, and was going to terrorize Miles... but Miles showed he was mentally able to go toe-to-toe with Harry with this scene.
