Reddit reviews Language, Thought and Reality: Selected Writings of Benjamin Lee Whorf

The film was adapted from a short story whose central conceit was the introduction of nonlinear time perception (via loose extrapolation of Sapir-Whorf linguistics and Lagrangian physics) to humanity by aliens. The short story would not have been written without that conceit. The film would not have been adapted without that conceit. You are trying to argue against the very reason the film exists.

I also suspect you really didn't understand the the film's message, otherwise you wouldn't be so quick to discard it. I might add that the alternatives you proposed make for a pretty uninspired, conventional plot. The point of the film is not to be awestruck and confused of the alien unknown, but to discover that you can empathize and communicate with it.

Also, your writing style is spastic, impressionistic, and kind of angry. So I'm really struggling to find any reasons to respect your opinion. Go meditate or something. Read a book. Make some pasta. Maybe take up painting. This movie would rather you improve your outlook than try to change what is already determined.
