A few months back The Young Ones was re shown on TV. I read a short piece in some local street press written by someone who had been a uni student when it aired and so was in the target market. Their point was that re watching the series 30 years on they enjoyed just as much the first time they saw it.
I wasn't around when the series first aired and so this was the first time I saw it. I thought it was funny in parts but nothing wonderful. Another point that the author made was that when their parents were young Monty Python's Flying Circus would have been the equivalent popular youth comedy and that their parents still found it funny years later. They pretty much had the same reaction to Python as I did to watching The Young Ones.
This got me thinking: Do you think that you only really enjoy youth comedy if your were in the target market when it was made? And what was popular when you were young?
So for me the comedies from my time would be Summer Heights High (Aussie mockumentry series), and I also really like The Mighty Boosh and The IT Crowd. The last two aren't overly popular in my part of the world but they seem to be considered youth comedy.
