Arrival follows linguist Louise Banks during a period when 12 spacecrafts mysteriously appear around the world. The aliens seem peaceful at first, and the US military has called upon Louise' help in order to try and figure out their language, and get the answer to the most important question of all, "why did they come to Earth?". The plot is presented in an intriguing manner, and it keeps up the suspense as you come to realize how difficult it is to learn and try to teach a language without any sort of context. The aliens are structured differently, culture is not the same and obviously the method of communication is complex. During the film, considering the events, you hope that it will be able to present a satisfactory conclusion because otherwise, it would feel like a huge waste of time. In this aspect, the resolution was acceptable, and while it wouldn't blow your mind away, the twist is interesting to say the least and explains some confusing plot points in the beginning. The film is slow paced but manages to keep viewers engaged, Arrival's themes are solid and strong.
