I'm just going to copy and paste my comments from Tony's review here, as I think they apply:
This entire arc has been forgettable, at least IMO. I'm glad it's over.
I know some people like it, but I can't see the appeal at all. I mean, this was such an amazing opportunity to update and improve upon Batman's origins...and instead we got something that was just mediocre.
I'm trying to judge it as it's own thing and not compare it to say, Year One, but even then....there are no memorable or stand out moments, and there really isn't anything that defines these adventures as Batman's origin. If these stories were not called Zero Year and were just flashbacks not given any special treatment, it wouldn't make a difference.
That I think, is the biggest flaw of Zero Year. Compare to Year One (dammit...), where you have a focus on Gordon just as much as Bruce. It slowly shows the corruption in the city at all levels, it shows the good men who are trying to figure out how to solve it, and finally it shows the revelation of a legend being born. Not a single hint of an aspect of that is present in Zero Year.
For as much praise as Snyder gets for "treating the city like a character", Year One fleshed out the city far, far more, by showing the effect on the characters who live there. Year One showed the city much better than Snyder has been able to, and it's much easier to see how everything that happened after followed sort of naturally after Year One. The same cannot be said for Zero Year.
I've been saying this from the start: get rid of Snyder, get rid of Capullo.
