I enjoyed seeing the Zoo Crew again (though NOT the ending), but I, too, was confused by what it was doing in "Titans." They could have done it in any book, really, so maybe Rhino was right. They realized early on they only had about 1 1/2 issues of story and instead of padding it out like all the other books do (some would have made that a whole six-issue arc), they found a cool idea for some filler.
I'd love to see a CC book again, though we'd have to retcon that out of the timeline. That was a crappy way to treat the character. Though I guess if you're a third-tier character these days, you can't expect to be treated well.
