Arrival is the cinematic equivalent of watching an artist paint his masterpiece. However, it takes the artist 100 years to finish, and in the end, it's still far from his masterpiece. While Arrival offers some unique visuals and ideas, this thing moves at a painfully glacial pace. This would be fine, if any of these characters were remotely interesting, or the story offered more than to just set-up a twist ending. Adams, and Renner, are really good here, which makes up for having to slog through the story. The film will have its supporters, because of its poetic nature. Ultimately though, the super slow pace, uninteresting characters, and twist ending, might not be enough of a reward for others.
