Yeah, season 2 of Mr Robot was a tough thing to get through. Very slow and indulgent.
Season 3, though, has been amazing - about as good as TV gets. The point at which it really ramps up is the fifth episode, Runtime Error, which is a continuous shot in the style of Children of Men and Gravity. I've never seen anything like that attempted on TV before. The following episodes offer edge-of-seat tension and wrenching emotion, with a sweet Bill & Ted song thrown in for good measure.
