Cheers - One of the funniest, most critically acclaimed, most superbly written and acted sitcoms ever to grace television. This is aimed at adults, although families with older children can watch it too, indeed, I first watched Cheers at the age of 17.
Sam, the lead character, is a promiscuous womanizer - not for kids! This being said, he is an example of what alcohol can do to you - he was an alcoholic. Diane and Rebecca are strong leading women, although Diane is somewhat snobbish and Rebecca can be a bit angsty. Carla, the waitress, is always hilarious with her insults, another thing younger children and teens shouldn't hear. Coach and Woody, whilst being somewhat thick, have warm, friendly natures and are good examples on how people should behave in general. Then there's Frasier and Lillith, everyone's favourite intellectuals, who are quite New Age and too progressive for young minds. Finally, resident barfiles Norm and Cliff - one's a resident alcoholic who's always bickering about his wife, whilst the other is a never-ending walking trivia book. Both add much of the humour to the show.
At the end of the day, under 15s shouldn't watch this, as along with the adult themes, it gives the wrong idea about alcohol - if you drank beer like Norm does in real life, you'd be dead by the time you were 40, if not before then!
