I don't think ppl remember the begning of the second season very well. The second season picked up after the 6th episode, before that were some standalones episodes. I mean, how much whining there was about how Moira's trial was boring/stupid/they should just get over it fast. Last season was a great season but there was a lack of character development and focus, I mean, Diggle was so much on the background just nodding, Isabel just disapeared for a long time, they putted togheter Thea, Roy and Sin as a mini team just to forget about them later. This season they are developing all the relationships and characters (really, it's been basicaly one episode focused on each character) before really picking things up as they said it will happen after the crossover.
