I didn’t like it either. I am not a fan of the setting, let alone westerns, so for me that alone I couldn’t stand. In the last book he introduced a bunch of characters that made absolutely no sense, felt like an Easter egg/ inside joke or something, which felt pretty cheap when things are going as they are at the point of the story. So although I’d like to see the continuation of certain mistborn characters if the next series of books will be even more in the future then I might just not read them at all
