I've been watching Mr. Robot since I first heard Leo Laporte and Steve Gibson talking about it on the Security Now podcast and I've been hooked ever since, watching the two part series finale was sad as most finales are. Praised for its mostly accurate depictions of technology and intense acting there's been a lot to enjoy on the four season journey. I don't want to spoil the show but I was disappointed with the ultimate ending (though season 4 tied up a lot of loose ends nicely). I still recommend giving it a viewing if you haven't already, many online felt the ending was fair.
From Wikipedia: Mr. Robot is an American drama thriller television series created by Sam Esmail for USA Network. It stars Rami Malek as Elliot Alderson, a cybersecurity engineer and hacker with social anxiety disorder, dissociative identity disorder and clinical depression. Elliot is recruited by an insurrectionary anarchist known as "Mr. Robot", played by Christian Slater, to join a group of hacktivists called "fsociety". The group aims to destroy all debt records by encrypting the financial data of E Corp, the largest conglomerate in the world.
