take your pick:
grumpy old man is forced to change his life in some way due to illness/family loss/old age. befriends young, intelligent, quirky child (either gender suitable) and learns new lessons about life and how to enjoy his last days. child's parents must be equally quirky for added indie benefits. for bonus tearjerk: child becomes ill/old man dies.
two (extras optional) women, preferably housewives are bored with their life and decide to take a roadtrip/get a makeover/have an affair. children are either of elementary school age and have apparently never seen a paddle, or adolescent and experimenting with drugs/alcohol/premarital sex. one wife will manage to rekindle her dying marriage by some miraculous turn of events, while the other will find new love with an old highschool flame. for bonus tearjerk: one wife becomes ill/child runs away/husband becomes ill.
a straight, white boy, and a straight white girl meet. hilarity ensues as they refuse to admit they're in love/know they're in love but are with someone else/break up and get back together. ethnicity of male can be changed only to african american. ethnicity of female must remain white. tips for pandering to every hipster known: boy is out of college and stuck in a dead end job and doesn't know what to do with his life. must listen to lesser known indie artists and girl must be pale and have a large vocabulary.
the world is in danger and only a teenage white boy/well-built man/team consisting of exactly one woman, three white men, and two token ethnicities can save it. bonus points: villain must be a mincing gay stereotype.
an angry lesbian kills everyone because her girlfriend left her for a man/she's in love with her best straight friend/she hates men. bonus points: angry lesbian is ugly as sin and therefore easier to hate. also, extra bonus points if angry lesbian turns out to be a self-hating trannie.
woman/man is convinced that she/he will never fall in love again after being jilted/losing a former flame. becomes bitter and cynical, possibly an alcoholic. refuses to see anyone else, despite the cajoling/threatening of friends and family. only after meeting a disgustingly attractive man/woman do they let their hearts open up just a tiny bit, hilarity ensues, including, but not limited to: a montage with cheesy 70s pop, a heartwrending confession, a drunken kiss, a split due to crossed wires, an end of the movie kiss. bonus points: potential mate is wildly eccentric and unaware of their own obvious charm and outward appearance. also, woman/man must have a horny, dryly sarcastic, unrelentingly merciless best friend.
no wonder no one goes to the movies anymore.
