(s4 spoilers) After s4 just came out and I binges watched the whole thing in one sitting, I can confirm that this show is undoubtedly the best show I have ever watched. You can tell in s4 how it has improved-character development, plot twists, the suspense, the Rivalry! The more deep conversations was a good touch too. Lots of emotional scenes where people cried, very surprising when Daniel snapped at Anthony for hiding another device. Also getting to know more about Anthony was interesting because in previous seasons he had barely any screen time at all. After the fight I thought that the show was over, that it officially had ended and there would be no more seasons, but I was completely thrown off. I assume that s5 will be even better, and my expectations are extremely high.
