Self-contained story serves as a perfect jumping-on point for new readers.
No critic ratings have been found for this issue.
I am generally very critical of overly expositional dialogue but it works here to really draw in potential readers for only 50 cents to give them a decent leg up on the story so far in Invincible as well as tie it directly to the story and explaining Mark's world to Amber. It's great. Invincible can get it.
That's a cool recap, it was nicely put in the main storyline. I'm not a fan of such comics, but it was fine. I'd just rather prefer it to be issue 22.1 or something instead of 0, it gets kinda confusing now, but I understand why it is what it is and I believe it worked well back then, it really feels like something that can make you interested in the story.
