“Ex Machina” is rightfully being called one of the best films of 2015 so far, and justifiably so. It is a thrilling psychological nosedive into uncharted cinematic territory, while harkening back to themes and the mythos of what makes a psychological thriller so exciting in the first place.

Domhnall Gleeson is Caleb, an employee at the Google-like Blue Book company. After winning a sort of lottery, he is invited to spend time with the company’s reclusive CEO Nathan, played masterfully by Oscar Isaac. What follows is a trip down the rabbit-hole, as we follow the characters discussing and discovering new moral dilemmas regarding technology and humanity.

After bringing about what he believes to be the world’s first artificial intelligence, Caleb is tasked with conducting several interviews with the android named Ava, played by Swedish actress Alicia Vikander.

Vikander’s background in ballet lends her character to an almost ethereal and otherworldly quality of movement. Every motion is precise and calculated, but there is a grace to her that seems superhuman.

Oscar Isaac, who not to0 long from now will be forever remembered as the cool pilot dude from Star Wars, has been on my watch list since “Inside Llewyn Davis” and proves to be one of the most talented actors of our day. He brings an intensity to Nathan that could all too easily be played as one note and purely villainous. But he so humanely portrays a man who, for his whole life, has been somewhat of an outcast, gifted only with money and genius intellect but a general distaste for human interaction.

The score, sound design and artistic direction of “Ex Machina” coalesce so perfectly that there is a rather unnerving quality of familiarity throughout the film. This future doesn’t seem far off and it’s not hard to imagine a scenario where something similar like this could be talked about, and that is perhaps what is most terrifying. It is an instance when all of man’s progress translates through the Stone Age to today, until we ourselves become gods in creating a new type of intelligent life. It’s a theme that science fiction has approached before, but never quite so viscerally.

“Ex Machina” is not only one of the best films of 2015, but after chewing on the film for some time now, it may be one of the decade’s best. I’ve not had my mind challenged in this way since “The Matrix,” and I can’t get enough of it.
