Season one we have no idea what’s going on but the beginning of season two we know too much for there to be much mystery. Yeah we don’t know Helly’s motives and what they’re working on but neither of those are as interesting as the first season’s total confusion.
Examples:
Random farm scene
Knowing helly knows
Season 2 is different from season 1.
Season one explored a science fiction idea, what if we could separate ourselves from ourselves.
Season two however is world building. Don’t get me wrong season one has that as well, for instance the weird Kier dinner in the house, but season two has world building as the focus.
Season two needs to ask all (many) of the questions that will pay off in the finale, so it needs to expand.
