Here's a thought exercise, of sorts: if you're disappointed in AG, how much of that is on the comic's own merits, and how much of that disappointment stems from what the comic is, or isn't, relative to QC? When I first discovered QC a couple of years back, it took me a few tries to get past the first couple hundred strips; the storytelling, and especially the art, were nowhere near as developed as they'd eventually become. Had I given up instead of finally plowing through, I'd have missed out on some good storytelling.
I suspect that the pacing of this is part of what's putting people off; the fact that it's not a gag-based slice of life comic like QC may also be a drawback for some. If you're new to it, it' s not like it takes long to get through the archives, and it's still very early in the story yet... the story and characters are still developing and maturing. But from the standpoint of the art and the story, this one's off to a much better start than QC was. I think it's early yet to pass judgment, but at the same time, I can't help but be encouraged both by what I've seen so far, and also because Jeph has generally been willing to change things up instead of settling into ruts.
