Yeah, I didn’t know there was a Jaws 3 either.
I’m not going to watch the movie, but I do want to point out some cultural differences that are quite obvious in this 1983 production.
The world was not dainty. The 1983 world was still substantial.
Everything looks like it was built to take some punishment. Nowadays everything is brittle or flimsy or both (is that possible?). A computer-communications room was filled with large pieces of equipment each having oodles of unused panel space. Things needed to be bigger back then.
Now very complex systems are built as a single chip! Some equipment is already as small as possible while remaining controllable. A tiny phone is no good if it’s too small to dial. New ways of using equipment will lead to the next diminution of size.
A few computers were shown. They all had large tape reels on top. That kind of storage today would seem glacial.
Cue the meaningless flashing lights. They had lots of flashing lights and none of the steady ‘confidence’ lights most equipment today has.
One more thing about this flick. Bad acting is timeless.
