I'm sure my perspective is very much shaped by the fact that I'm not done yet. But I do get a bit of the self-insert vibe I get with SS. I'll reserve further comment til I finish the series, but I suppose it was on my mind and I was curious about the appeal.
What do you think of him so far? Do you think he is well-written complex villain?
But yeah, my answer is a little bias b/c I've finished this series a while ago (years). What made you watch the series now? And do you plan on watching Korra afterwards?
