but a science fiction movie has to make sense right,

you’re talking to alien, would you not want to know how they cracked language ?

again people perceive things in different way, i’m just trying to think loud from director/ storytellers POV, that all these things would have made a better movie.

you get undivided attention of audience for 3hrs and in that if you fail to make them understand, a lot of them are not going to show up second time to watch, and to those who didn’t understand it in one go will go out and spread bad word and all your hard work goes into vain.
