I expect a lot of people will compare this to Ex Machina, and for good reasons. Excellent story, interesting character development, great acting and directing, this is definitely the kind of smart, evenly paced sci-fi I love (if you're expecting explosions, lasers and flying car chases, you're gonna have a bad time...).
While it may be using familiar tropes and the occasional cliche, this truly is a 7/10 throughout that earns its 8th star in the last 15 min. Highly recommended, especially for sci-fi fans!
