I finally watched the last episode. As I expected Lange was amazing she brought such a depth to the many sides of 'sister jude'. But as I look back on the whole season I feel like it went from 0 to 120 back to like 50. The ending did nothing for me, but as i've said before the whole alien thing threw me off.
I'm hoping the next season will be more up my ally. Witches would be awesome!
