One, I’ve said over and over that leaping off tall buildings isn’t allowed any more because too many hack directors have done it. (Damien Chazelle is obviously not a hack so I don’t get it.) Two, it’s okay to rescue a character from terrible death at the last instant, but the manner of rescue has to make some kind of spatial sense. If a guy is about to become instant hamburger on the pavement due to falling 50 stories, he can’t be saved at the very last instant (10 or 15 stories before impact) by a woman who wasn’t in the scene to begin with. You have to set this shit up, and then pay it off. And three, you can’t just stop a body falling at 200 mph by hugging them. This is cartoon stuff, Road Runner vs. Wile E. Coyote.
