Distinguishing features of short film as opposed to feature film

Short films tend to be more condensed and focused than feature films, which can contain extraneous elements. Short films tend to be overly simple or kitsch. But they also have the ability to make more strong and more profound impression on the spectator than feature films. This is because of short film's inability to by any means comprehensively explore a subject matter, which leaves the spectator to fill in the blanks. In this way short films have the potential to immerse the spectator more in their message. That's why short films are often open ended and short films with open ends tend to be better received.

In short films, it’s easier to choose every element with precision, every prop, scenario, line of dialogue has more ability to hang in the spectators mind purely on account of their scarcity in comparison to longer films.
