The main character's life (Jim) is teaching during the day and dancing and picking up partners at the discos. And this process is shown over and over again, ad nauseum, with the discos playing one of literally four very repetitive songs in every scene.
This film desperately needed an editor. It's a 20-minute film that goes on for an hour and 50 minutes. There's literally just 15 minutes of consequential footage in it, and I've never seen so much disco dancing footage in a single film in my life. Even Saturday Night Fever didn't have this much.
There's one shot of Jim scanning the crowd while he drinks his beer, and the shot just goes on for literally 5 minutes of him staring and pretending to drink from an empty glass with his eyeballs zipping around as the camera slowly zooms in. I could almost imagine it being a Python sketch where satirical subtitles appear, saying, "Okay, you can cut now."
"No, seriously, cut."
"Okay, cut, please."
"Will you please stop drinking from an empty glass?"
"No, seriously, there's no more beer in there."
"You're literally licking the glass clean now."
"Okay, CUT!"
Yes, I appreciate the film as a time capsule and for its honesty and cinema verité style, but it's a film that doesn't know when to quit for lack of interesting material. The only consequential moment is the scene in which he answers questions about his homosexuality for his students.
