The genre, or rather direction in the movies of the mid-80s "yuppies in danger" lived short and bright. The essence is to throw the representative of the newly appeared social type - yuppie - out of the world of stuffiness, which is dear to his heart, to hell, into some light crazy adventure. Yes, echoes of this idea can still be found today.
"After Hours" is the pinnacle of this trend, absurd and wildly entertaining.
From the very beginning, the main character has a hell of a lot of luck. That the pen stops writing, a twenty in the window flies out the window, etc. Very self-ironic. To hell with conventions!
In general, simple in the beginning of the story grows into such devilishness, from which you get puppyish pleasure. I was, I'm sorry to say, just laughing. Everything is very witty and intersects in the most unexpected places. In Scorsese's career, it's a very special picture. It's criminally underrated, and it's so beautiful.
Two words: fast and uncluttered.
