Jumping to sci-fi.
Scenario: your average mission to save the Earth from ultimate destruction.
Premises: it's such an important, delicate mission that the NASA recruits 4 people (not 12, or 25, nonono). One is a retired atronaut (eh, the experience of the old generation!!), a young woman who dresses like a man and is the only one capable of piloting a spacecraft, an engineer with glasses and some cowboy or dockworker whose knowledge of physics and astronomy equals zero but he's got the guts and will entertain crew and viewer with the most idiotic questions about the solar system.
Plot: the engineer will fall sick with chickenpox 1 hour after departure - and why not? After all, they are not checked, or prepared before the launch in real life!
When the game gets tough, our old astronaut will take over the piloting of the shuttle because he's the only one who can do manual steering. 345 millions problems will complicate the original mission, including meteor showers, an engine which breaks down, no connection with Houston, the bomb didn't work, "ops, we didn't think about the absence of gravity (we thought it was a school trip to Niagara Falls) and now we must re-do all our calculations. Manually."
They come back by miracle in a spacecraft which, after losing all its pieces looks like my niece's pedal mini-car and land into the ocean. The sun shines again after 2 months of darkness. Like this:
