Telika: Floppy disks, and computers having floppy drives.
The CD revolution (the first CD you owned, ooh, rainbow effects, ooh, skip right to the track you want).
Light-hearted heroes and action movies. As opposed to gritty, badass, and "so realistic".
High-pitched male singers - horrible more often than not.
Unconscious and uncriticized ordinary racist and sexist tropes.
Stunts. "Oooh, it's a tv series with STUNTS". "Ooooh that car did, like, jump on a ramp". "Oooh an explosion".
Phone booths.
Also : joysticks. Also : A MOUSE.
Material movie f/x (here's a shot of the director next to the spaceship model he used).
Hope for a better world, progressive ideas, "asylum seekers" and "refugees" being perceived, by default, as decent people righteously fleeing a creepy country. Note : the countries are still creepy, but people are now supposed to stay in them.
Pollution ? What are these guys even talking about ?
I seem to recall some such things, but I'm nowhere near 30.
