I'd post my opinions but they basically line right up with the article, though I haven't watched Arrow since season 1 and Walking Dead Since season 3.
Flash has had a great start, Gotham is a bit of a mess at this point and is saved almost solely by Robin Lord Taylor's Penguin, Constantine is so-so but it's early days, and Agents Of Shield had continued it's general upswing from late season 1 and is a decent show, dealwithit.gif
So you're rating a show this season based on what you thought of it last season. Makes total sense.
