3.5 stars.
Okay, this was fun, I love the Clint/Bucky team-up and the quest for Natasha. I, like I've said before, am so lost with the current marvel events/storylines, so I had no idea about Black Widow's... ya know, demise. But this gives you enough backstory to bring you up to speed and enjoy this comic.
The relationship between the characters, Clint annoying the shit out of Bucky and Bucky low-key boring him/making him uncomfortable was the best thing out if this and tbh the selling point of this story, and it does deliver some amazing moments/lines (if you're on tumblr, I bet you've seen the "naturally greasy" panel) Plus, the whole Red Room plotline was actually entertaining, although maybe the weakest part, specially with how quickly everything was resolved.
That being said, maybe because I do love Clint so much, I felt like he got the short end of the stick and the ending wasn't satisfying enough. It sets up for more, but I have no idea if the story continues with another title. Dunno, it was never a 5 star book for me, but the ending really disappointing me.
