Yeah I just finished it. It was pretty meh but a meh Astro City is better than Age of Ultron condensed to 1 issue which it probably could be. I've also never really liked the first issues of any astro city though.
Maybe you're right, I did feel a little underwhelmed by it. Only time will tell. Part of me wonders if Astro City will remain relevant. It didn't really start out of the gate strong this time, if I never found out what happened after issue 1 I don't think I'd wonder much. But you gotta give Kurt Busiek a little more credit, I suppose..
