Since I kept hearing some really good things about this movie, I was really eager to check it out. Well, eventually, I wasn't disappointed and it turned out to be easily the smartest movie released in 2015. Indeed, even though it was visually quite appealing, it was above all the fascinating ideas developed in this picture that really appealed to me. As a matter of fact, just a few weeks ago, I saw a talk show on TV where they were saying that, indeed, some big companies like Google are currently investigating on AI and we should expect some major breakthrough in this area in the near future. In this movie, you can see already the issues if we would come up with a very intelligent AI. For example, how could we know what an AI is actually exactly thinking? What would be its purpose in life, a concept we humans are constantly struggling with? And most important, what would be then our purpose? Eventually, there were only a couple of things that still bothered me though. First of all, even though Nathan seems to be a genius, how come he doesn't figure out that Ava is responsible for the powercuts? It was seriously pretty obvious. Also, why would Caleb believe every single thing told by Ava without finding anything slightly suspicious? But those were some small issues, it was really a brilliant SF feature and it is definitely worth a look, especially if you like the genre.
