The Atlantic: "Lost. Sons of Anarchy. Grey’s Anatomy. 30 Rock. The Office. Justified. Glee. Parks and Recreation. They are some of the best, most celebrated, and longest-running shows of recent years. But they also have something else in common: Even their most ardent fans would agree that each of these shows had their strongest, most memorable seasons in the second or third year of their respective runs. And while most of the actors and producers dream that the new shows they are promoting to reporters at the Television Critics Association’s summer press tour will be on the air for many years to come, the truth is that more often then not, those shows will peak creatively sooner rather than later."
Fight For Paradise Review: This reality show is nothing new but there are so many uncomfortable moments that will definitely give you the ick.
Bros Review: The series, as the title suggests, is about two adult men who want to behave like children and we are not here for that.
Going Home With Tyler Cameron Review: This is a simple, no-nonsense but cliched watch, with Cameron's boyish charms taking centre stage.
Good for Arrow then. Can't wait.
I'd say it's probably also due to business. After season 3 most people don't even know if they are keeping their jobs much longer since most shows are canned shortly after no matter what.
