Saturday Night Fever -
https://www.imdb.com/title/tt0076666/reference/
Where to begin.
Ok well the script was inspired by a famous article that described the lives of newyorkers who were growing up only interested in doing their 9 to 5 and then throwing it all away at the weekend; while this was complete bullshit, people read it and thought "hey, *I* want to throw away my weekends dancing" and between this mania and the film that followed it, SNF was a huge thing during the early 70s.
The story is of Tony Manero, young italian from old-skool immigrant family who, well, does exactly that - works 9 to 5, and then can only think of dancing; not only that, because all his friends are caught up in this living life meaninglessly thing, but Tony he's *really* into it. He even pushes away his would-be GF Annette because she thinks more about Tony's cock than about dancing. In fact, he "cheats" on her with much-older Stephanie, a city woman who has got her shit together, but is also able to take dancing practice seriously.
There's this weird triangle at the center of the film. Tony is loved by everyone and all the girls want to have sex with him, Annette the most. But Tony "desires" Stephanie; not as a sexual partner, but rather as a dance partner.
Being that Stephanie is older (and kinda repressed) she thinks Tony just wants to have sex with her, because she can't understand someone from a culture so ignorant, they actually want to invest their lives in the weekly dance-a-thon at the disco down the road.
To hammer in this plot even more, the film also shows what a bunch of losers all of Tony's clique are. From the father that worked himself into a grave, the brother who `has been living life the way the family wanted him to, the guy who can't get a girl, the guy who can't get a job, the girl that just wants to get married.
In the end, one of the side characters kills himself, so that Tony can have his breakaway moment and try to maybe actually do something with his life.
From a production perspective, the film is .. ok. The issue is that the film pretty much runs out of good ideas halfway; Tony ditches Annette for Stephanie, they have the dance, Tony gets the prize but in his mind, he lost to another couple because to Tony, dance is everything.
This is only about half of the runtime; the rest is not only not as interesting, but it's also shot and paced shoddily. And unfortunately, you're gonna have to watch the whole thing. Also, John Travolta's dancing, the music of the Disco, and the actual disco sets are the best parts of the film, all of which are in the first half.
All in all, i would give SNF only
7.5/10, of which half point is for cultural importance; while it may have been massive at the time, not much of it has remained in today's world. If you've never seen it, you could probably skip it and not be any worse off for it.
