Pardon the pun, but I always come away from each new volume of Copperhead feeling like I was just on a blind date with a snake oil salesman. Like, everything seemed good while I was in it -- and then the thing is over, and I feel like I've been had. It's just that Jay Faerber seems more concerned with cliffhangers and punchlines than he is with actual story. I don't mind how goofy and simplistic Copperhead is -- the outlaw aliens, the Boss Hogg-esque villain, the sheriff-deputy rivalry, and even the sexy clone frontiersman -- but I do get a little exhausted by the zingers every issue, so extreme that at the beginning of every subsequent issue, Faerber has to devote precious pagespace to undoing the crazy thing he did at the end of the issue prior.
It's tedious, and Cv3 complicates this further by trying to tells its story in four issues instead of five, despite the fact that even when Faerber wrote five-issue arcs for the first two volumes, he really struggled to pack an entire story in.
Even though reading Copperhead always makes me feel kind of used and gross, the first two volumes were strong enough that feeling gross didn't matter. But in v3, Faerber attempts to juggle two subplots (the requisite crime-of-the-week, plus the requisite mysterious-sheriff's-mysterious-past-comes-back-to-haunt-her-metaplot), predictably not doing great things with either one.
v3 has more weird alien designs per capita than the previous volumes and gets points for that, but otherwise it's all just kinda half-baked. And more than anything else, Image needs to stop collecting less than five issues in paperback form. That only works with X-Men comics, and Copperhead, let me tell you -- you ain't no X-Men.
