Arrival

This isn't a typical alien movie. The plot is very cerebral. It can be hard to follow at times, because there isn't much segue between scenes. They'll explain something complicated very fast and it doesn't give you much time to process what just happened before they move on to the next thing. It's like that matg teacher who after explaining a complicated concept asks "Does everyone understand?" and moves on even if only 1 kid said "Yes." The plot has a lot of subtle forshadowing, some of which came from supposedly throwaway lines that ended up being important later on. The twist at the end was very well concealed, although I would have liked them to explain the reasons for why this twist can happen. It was brilliant, but came out of nowhere. 

Grade: B.  8/10  4/5 stars
