Arrested development has seemed for quite a while to be a main source of movie humor. "Sideways" comes to mind that way.
Considering the way adult male authority appeared in a lot of TV shows (60s and 70s) led me to think that the screenwriters were enacting their own conflict with their bosses, men who made them cut down on risque jokes, nixed plot lines, etc. And those weren't great years for adult male authority in politics.
In many "teen movies" of the 80s you can feel the scriptwriter working out his/her issues with authority. John Hughes was pretty bad about this, however iconic those movies may have been. I learned to be thankful for movies where teenagers were depicted as whiny, know-nothing, irresponsible kids -- and celebrated for it.
