While Arrival is emotionally complex, it's also not very original or "sensical" with cliches and the overblown importance of Amy Adams' character - a couple other countries arrive at the same conversational point first with their linguists and the whole mahjong thread is both wrongly simplified (it's a game of win/lose) and impractical. The immersion in a language giving you superpowers? The reuse of the final shot of (the movie) Enemy midway in the film? The purpose of the other ships (oh, earth distraction?). The implication you can have the concept of weapon without the concept of tool...it's fundamentally broken storytelling. The attempt at realism (a la Close Encounters) but with a demonization of the military and mischaracterization of breaking quarantine rules (taking off the suit initially would have gotten her removed, obviously and limiting a word list wouldn't be a concern and is forgotten quickly as the herring it is). Just a sloppy movie that's a vehicle for an M Night Shyamalan trick. It might as well all have been a dream sequence and it's the exact same movie.
