SEASON FINALE: WGN America’s first original scripted series ends its season tonight, but fairly valiantly. It’s already earned a renewal for Season 2, and it packs tonight’s season finale with enough cliffhangers, revelations and bloody confrontations to make it move briskly from start to teasing finish. Not every character will survive the hour – but those who do are brewing up more trouble than ever. Double, double, toil and trouble… Janet Montgomery, Shane West star.
