Which side planned better solution for communication approach

Rating: 10/10 (16 January 2017)

Well, during the film, I witness an intense struggle between the proper academic preparation of communication plan with linguistic study on one side, and well prepared approach to communicate with humanity on other side.
We could easily draw lines with Spielberg's Close Encounters of the Third Kind, but Villeneuve's psychological approach was more intensive.
Tha cast was fine, physics were great and cgi was well made.
I can say I am the average sci-fi fan, and for me this was one of best films this year and one of best this century.
10 is my humble estimation.
