Well, this was certainly stylish, but it left me feeling that the entire season was pointless. I mean, the big reveal in the finale was that everything the characters spent the previous five episodes struggling desperately to achieve was explicitly, in-story, a complete waste of time pursuing a totally pointless goal. And ultimately the whole season was nothing more than a relitigation of the finale of season 1. We ended up where we started, which I guess they warned us about by naming characters Mobius and Ouroboros, but which is still frustrating. The only thing at the end of season 2 that's significantly different from where things stood at the end of season 1 is that Loki is apparently the God of Time now, which is a random character development that doesn't feel like it grows out of any kind of journey he's been on, because Loki hasn't had any personality all season, he's just been reacting to the plot.
Also, what the hell? How are actual parallel universes somehow physical vines that Loki can grip in his hands? I mean, "timelines" as a convenient visual metaphor are one thing, but this was taking it way too literally.
Ultimately, it just doesn't feel like we needed this season. It's just an extended, wheel-spinning epilogue.
