1.)High schools are always named after the small town where they are situated. For example if a place is called 'XYZ-ville' the high school will undoubtedly be called 'XYZ-ville High'. Duh do not expect the founders of American high schools to be endowed with a better imagination.
2.)The male and female protagonists would invariably have a troubled past, i.e, either their parents died or divorced when they were kids or he/she is an illegitimate child. This of course has inflicted a deep emotional scar on them which usually manifests in the form of them smoking pot or engaging in illegal activities.
3.)No high school would ever have a uniform. I mean how else will all the hot girls get to sit in the most provocative of poses, sporting the shortest of skirts/shorts and cleavage-displaying blouses?
4.)High-school students are perpetually 16-year olds. Doesn't matter even if the lead actor looks like he could be married with a 10-year old. He is 16 and you gotta believe it and fawn over him.
5.)The female protagonist is mostly a brunette with a miss-goody-two-shoes air about her. (Let's call her Miss GTS for convenience shall we?) She might look extremely ordinary but all the hot guys would fall for her faster than you can say 'Yes we can' ignoring the advances of the dumb, bitchy blonde who is hot but nonetheless the 'bad girl'.
The perfect Miss GTS
Miss Mono-Expressioned...err Bella Swan from Twilight
The dumb, bitchy blonde
Caroline from The Vampire Diaries
6.)The thuggish looking popular jock - blonde if he is the ill-famed bully, dark-haired if he is the guy-about-to-have-a-change-of-heart, who will ditch his blonde, conniving girlfriend and transform into a good person thanks to Miss GTS.
Classic case in example
Finn Hudson from Glee
7.)Even though Miss GTS speaks of 'true love' and appears to be a loner with a solitary best friend (who will be an African American/nerdy girl with glasses without fail) she is always plotting inventive ways of getting to jump the hero's bones. Alternately our innocent Miss GTS keeps switching back and forth between two hot guys.
8.)The slut who gets herself pregnant or is doing drugs and gets lectured on about how one should lead her life by Miss GTS even though her own life is pretty much screwed as well.
Adrianna from 90210
9.)There's always the dorky teacher who takes no bullshit from his students and as a direct consequence of that, is labeled as one who doesn't understand the 'issues' centering a teen. There's also another good-looking, charismatic young teacher whose side-job is to go around offering free counseling to drug-addicts, pregnant teens, the Goths and other social rejects on campus. (Dude, you could seriously consider becoming a therapist as an alternative career option)
10.) And lastly no matter what, high school students must never worry about education. They will attend school in the skimpiest of outfits, gossip in class or make paper planes completely ignoring the presence of the teacher, conspire against the good people, join the football/basketball team, worry about part-time jobs and which party to attend during the weekend, make out in front of lockers. But what they must never do is study. It's against the universal laws governing high-school dramas.
P.S : I was absolutely smitten with the Twilight books a coupla years back but seriously...the whole vampire-human romance angle has started to get on my nerves. Oh and somebody provide the makers of crap teen dramas with some innovative ideas. For our sanity's sake.
