I initially avoided this show because I assumed it would be boring. Plus I didn't know anything about hacking and I thought that I wouldn't enjoy it because of that.
Boy, was I wrong.
This show gripped me immediately. It has a perfect pace (in season 1, anyway) and kept me up all night clicking "next episode." The cool camera angles and cinematography aside, the story is well crafted and the characters are original and interesting. Rami Malek is a great lead, but let's not forget Christian Slater pulling off the crazy guy with "good" intentions. Actually, there are a lot of great characters, all with their own moral compass and justifications for their often questionable actions. There are twists and turns and moments that left my jaw dropping.
This show is 100% worth watching, and I only wish I had started it sooner. I left off a star because I have only seen the first season so can't really speak for the other 3.
