As someone who has read Unmarked, Restart and Limited (side stories included) in a span of 3 days, I can only say...
DAMN
I'm honestly impressed with how much the writing improves after Vol 1, even if the formula stays the same. I did not expect this kind of ride, but I definetly don't regret it, even if it hits you hard sometimes.
Also, while it doesn't always succeed, I do appreciate how the series can catch you off guard more than once.
Its not exactly perfect in storytelling and feeling (Limited felt like an american action movie/comic book way too often), but the pros far outweight the cons (The last part of Limited was brutal, beautiful and tragic at the same time), so I'm definetly sticking with it.
Going into Jokers now, and apparently, more Snow suffering...
Oh, and to all of you, merry christmas from your local, very, very morally dubious aspiring reformist
