All roads lead back to Defiance.
It's been the better part of a year since Defiance wrapped up its first season. Accordingly, nine months have passed in between the Season 1 finale and the Season 2 premiere. In that time many characters' fortunes have fallen, while a few have risen in the wake of the Earth Republic taking control of the city. "The Opposite of Hallelujah" is largely devoted to reacquainting viewers with the main players of Defiance (those who survived Season 1, at any rate). It makes for a comfortable way to ease back into the series, though it's not the most exciting way to kick off a new season.
