These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternate Character Interpretation: How truly evil are the aliens supposed to be? Despite the fact they are obviously manipulating humanity, they don't do anything overtly malevolent throughout the film, with most of those actions actually being done by humans themselves. Why do they bother telling humans about the conspiracy? It's clear they don't need to reveal themselves, or else why bother with the hypnotic signal in the first place? Also much of what we are told about them is contradictory at best, such as the scientist's idea that they're xenoforming Earth's atmosphere to match their homeworld, which begs the question of why, given that they easily can survive in Earth's own atmosphere anyway?
