Granted, one must suspend a sh**load of disbelief to enjoy this series. Outrageously epic-scale set of villains and villainy; Morena's impossibly broad and complex plot to expose the baddies, foreseeing, if not creating, a zillion variables on multiple fronts, allowing her to occupy a prison cell as if it were her throne room as events unfold.
This program would have been too outlandish to stick with but for Morena's charisma. The same was true for her turn as the head alien in the V series, but even moreso here, despite the distraction of a weird and inconsistent accent. She does smug and inscrutable while keeping us in her corner better than anyone I can think of.
But... her meticulous planning that made the first nine hours compelling was completely abandoned in the finale. The ending can only be justified by knowing they'd be renewed before they shot it. If they didn't, the last 10 minutes with hanging plot threads are a betrayal of those who spent hours investing in the principals and the outcome. Very disappointing.
