how to (short) story?

How difficult is to have a short story that makes you feel something and with the same intensity as a very good novel or the best movie.
My memory is not good at all so I think I was looking for the best short story and because Umberto Eco is one of the masters of storytelling and one great theorist of it I read one that he recommended but right now cannot remember the name and the author although I read more amazing shorts buy the guy. I (hope) will come back with the name(s).

Anyway was about the way to start and end, to arrange and follow the elements, ideas and actions int he short story, the setup and characters...
And this short story is well written no doubt.
And it touches the readers into, onto, one primal emotion :)
Which it should, like a good story.

Part 2: in which there is this guy that goes on his bike, its snowing but he is thinking and not paying 2 much attention to the conditions...
Nevermind that but I was thinking next that even if you have a good written story with all the elements BUT is in the future on SF many people would not like it.
And I do not mean people that do not read good literature.
And I do see a reason behind it, check this example: if you set Romeo & Juliet in a place with dragons or 1000 years in the weird gadgets future people will like it , of course, but will not feel the same intensity on it. I think. Because they will not identify themselves so much to the same degree with the context and all.
Don't get me wrong I do like or even love SF and fantasy stuff.
But I think our subconsciousness is conditioned by our century context,  more or less, in which we are born and raised, in the similar way in which we perceive something as beautiful or ugly because in our lives most people pointed to same type of beauty or ugliness, being a person or a  monster.

(a quote: "According to Immanuel Kant, beauty is objective and universal (i.e. certain things are beautiful to everyone). But there is a second concept involved in a viewer's interpretation of beauty, that of taste, which is subjective and varies according to class, cultural background and education.

In fact, it can be argued that all aesthetic judgements are culturally conditioned to some extent, and can change over time (e.g. Victorians in Britain often saw African sculpture as ugly, but just a few decades later, Edwardian audiences saw the same sculptures as being beautiful).

Judgments of aesthetic value can also become linked to judgements of economic, political or moral value (e.g. we might judge an expensive car to be beautiful partly because it is desirable as a status symbol, or we might judge it to be repulsive partly because it signifies for us over-consumption and offends our political or moral values.)").

So, like that, a Romeo and Juliet in Game of Thrones setup might not trigger the same intense sentiments. But even if it is fiction and it is set in the past people would feel it can be real, and cry and all that. Does that mean that a story should take this into account? I think is somewhere in between, because for me, for example, it does not matter to much, and I say that because I saw it is true, (almost) it does not matter what is the movie about, if is well done and acted, and it does not matter the time and place, it can lead me to catharsis!
But from early age I read, a lot, SFs and fantasy novels, from Jules Verne to Russian SFs :) that I could find in communist times.
So I guess, from an hedonistic point of view, I am lucky.
