Why are 'they' here?

Are these species here to destroy something, or everything? Or are they here to befriend us? “Why are they here?'' -- as the poster suggests; they mainly have something else in mind, which forms the crux of Arrival.

The Denis Villeneuve-directed feature takes it's own pace to unfold. Neither it hardly, though arguably, stretches any moment which may seem undesirable, nor does it jump to any conclusion thereof.

Amy Adams shines upon a realistic persona as the linguist Louise Banks. She seems less-concerned about her surroundings (until of course, they arrive); and in one scene brave enough to mix-up vague historical facts with the Colonel (Forest Whitaker) just so she can prove her point. Call her immoral on this, she likely knows how to get things done.

The tizzy soundtrack sometimes looks forced, but is mysterious, too.

Arrival, mostly is the result of how it was supposed to be made. Some scenes might be merely forgettable; some scenes are worth contemplating to. It’s a good+ movie, but maybe lacks the somewhat non-extra terrestrial touch to connect with the majority audiences. Or, was it not meant to be so?

Well, Arrival has mighty important, thematic message(s) to give to the audiences of our universe.

(Though originally released in 2016, Arrival was re-released in early 2017 in select theatres of Mumbai, likely due to it’s warm approval by the year’s Academy Awards).
