A movie or TV show that can be pitched in one sentence is called "high concept," which it is usually anything but. A fly on the production office wall heard these:
Misery: If Mama's not happy, ain't nobody happy
Casablanca: You can't always get what you want
Seinfeld: No hugging, no learning
Will & Grace: They're hanging out for love, and they'll hang that way forever
Twin Peaks: Who's your daddy?
Everybody Loves Raymond: My mother, the monster
The Flintstones: The "Honeymooners" with a better standard of living
