I saw Arrival. There is a lot that I enjoyed about it. It is a visually stunning film, for one thing. The first good look of the alien ship is a Magritte painting come to life, and the aliens themselves are imaginative, awe-inspiring, and are a refreshing break from the convention of making all benign aliens look reassuringly cute. The score is magnificent, itself alien enough to induce its own fair share of awe. And Amy Adams’ performance as Louise Banks is as powerful as it is understated.
All of these are very good things. Should you see the film? Absolutely. Having said that, I have some reservations. Spoilers follow, and I’m going to talk about the ending, so you have been warned.
