Yesterday I saw Alex Garland's new film, Ex Machina, and LOVED IT!
This is actually Garland's first film as director however he has extensive screenwriting experience for Peter Boyles's films, "28 days later", "Sunshine", "Dredd", and "the Beach".
This film is true sci-fi in the style of Blade Runner, the Shining, and Alien with deeply philosophical and existential undertones. It is a slow burn with only 3 main characters (plus an important fourth character with no vocal lines). Similar to Ridley Scott's "Alien" and Kubrick's "The Shining", the setting is a very important part of the story (an isolated and stark Alaskan compound).
I loved this film and found it very satisfying and engrossing because the performances are excellent and the writing top quality. This is sci-fi morality at its best with an excellent cast, acting, and script. This is also an excellent example of a synth only score done right.
