I liked it, too. What's interesting is that in a lot of ways, this Black Widow run reminds me of the current Daredevil run, even though neither of them has shown up at all in the other's book.
Anyway, am I the only one laughing about how we all tried to predict which person in Natasha's life is "the only man the Black Widow fears" and then it turns out to be a new character altogether? So long to all of those theories!
