Not lurking is such a hard habit to break. Especially with the way Reddit sorts comments, I’m so used to clicking into a thread to find some insightful discussion or hilarious joke that had already been made. But I’m trying my best, even by writing this comment!
Having just watched it last night, I had the same gripe as you did regarding the titan changes coming undone, but now I think it kinda works well with the shift in tone we get when it’s revealed that despite the events that took place, the cycle is doomed to continue.
