23. 'Halt and Catch Fire' (AMC)
A boom year for second seasons, at least for dramas that did not involve Colin Farrell in a Sweaty Sensitive Cop mustache. Halt and Catch Fire was already a perfectly captivating yarn about computer pioneers on Texas' Silicon Prairie in the early pre-Mac 1980s. But it really took off the second time around, as Mackenzie Davis' punk girl Cameron came to the center of the story, taking over Mutiny and trying to strike gold at the dawn of the Internet, turning the tiniest tech details into geeks-keep-swinging dramatic twists.
