I implore anyone who hasn't seen this to watch it. It's not very long, 3 hours split across 6 episodes. That's a couple of podcasts, or less than half a season of Friends. You can easily get through these.
You'll stop caring about the 80s quality of film and wardrobe once you start to lock on to the humour in this. They made this series so well.
And here's individual episode links if the playlist is inconvenient for you.
