Quantico
No gay sex, just interesting characters and so many twists and turns in a terrorist conspiracy amongst a new group of FBI trainees that you can't stop watching. My friend and I binge watched the entire first season in two days because once we started, we couldn't stop. It's in a similar vein to How To Get Away with Murder and The Killing, with so many pivotal twists that it keeps you guessing up until the very end. The thing I loved about Quantico was the flashback overlay between the current Alex Parrish who wakes up in the middle of a terrorist bombing in the heart of New York City and immediately framed as a terrroist and the past Alex Parrish who starts her new FBI training at Quantico and gets to know her fellow trainees (including all of their dark secrets).
