Sometimes, a bit of a break from a television series could do you some good. After all, your initial audience have blinked a couple of time and refreshed their eyes. You’re writers have shaken their wrists and come up with some new ideas. Your actors are all chilled out (I gather this was probably all filmed before the holidays but you get the sentiment). Generally, picking up where you left off has its merits. Gotham had a whole month to put its gigantic plot hammer down and start delicately weaving background, exposition and really enhance its characters that, in case you missed it, were soon to be Batman characters.
Instead, with it picked up an even bigger hammer and went smash, smash, smash on audiences head.
