This review may contain spoilers. I can handle the truth.
9/12 of its length Arrival is an interesting and thrilling movie about the importance of communication and the looming consequences of its failure. The rest is tad shortcutting "I can see future" anti-climactic mess that bored me.
Most interesting take out of Arrival is how the Aliens coming to Earth pose no visible threat being locked inside a stationary pod. It's the people and particularly the media driving people to the edge of chaos. Talk about responsibility in this scenario. One could also draw allegories to mass immigration and post-truth era – that's another story, though.
