Telling a Whole Story In a Few Minutes...difficulties/benefits/how it works

The difficulties in creating a short film in a few minutes is that there has to be the right kind of story. It has to be well thought out. If the story is not strong enough then there is no point in creating the short film. Although in saying that if you have a good story but awful actors then the story will be useless.
It also depends on the editing and the diegetics and dubbing over when there is noises in the background and it's difficult to hear the speech.
There is the problem of having this huge idea but then having to fit it into a 4 minute time slot. Although this can be good at the same time because you can then use the best of this great idea and start it from the middle or the end or the beggining and throughout we have this idea that there will be a cliffhanger and you leave the audience wanting to know whats going to happen.
With the short storyit's so impoortant that there is a narrative that is clear. For example Vladimir Propp's theory of having:
A protagonist-Leads the narrative, is usually looking for something (a quest)
A antagonist-gets in the protagonist's way
A heroine-becomes a prize for the hero
A father-an authority figure who offers a reward to the hero for completing their quest
A helper-often acts as a sidekick
A donor-gives the hero something (a clue, or powers etc.)
A mentor-teaches and guides the hero.
An example of this would be:

The Protagonist is Burn-E, the Antagonist is Wall-E and so on.
