Signs the Movie You’re Watching Is a Good One

(Inspired by this.)

It contains one or more of the following: a Technicolor fashion show sequence, an ugly-duckling-into-swan transformation, a rise-to-fame montage, a time-lapse scene of people fixing up a house or garden.

In one scene, a woman goes to her opponent’s house for a confrontation.  The opponent responds in an unexpected way, and soon the two are leveling with each other over drinks.

Much of the action takes place at a country house, on board an ocean liner, or in a gleaming Art Deco hotel.

Any people earning a living as servants are fully-developed characters with their own agenda.

At least one character is affiliated with an ancient and noble seat of learning.

Someone goes for a ride on a library ladder.

A cruel-tongued old baggage, who’d be a real pain in the neck if you knew her in life, refuses to hold back about the other characters.

Someone hastily gets married, in her mother’s old wedding dress.

A sudden storm forces two people to take shelter in a gazebo, where they dance; a church, where they embrace; or a disused cottage, where they light candles and fix up an impossibly good meal of tea, crackers and sardines.

A house contains a dusty room that’s a shrine to someone long gone.

One of the characters proves her goodness by giving a deprived child a wonderful gift.

Two characters who have had a somewhat fraught relationship are travelling by train.  They fall asleep on the journey and when they wake up they are leaning companionably on each other.
