Justice League 3000
I gave this the benefit of the doubt because I loved everything that Keith Giffen and JM DeMatteis have collaboratively written since 1987.
This goes against my better judgement because it is simply awful after two issues, and I do not buy awful books. Yet I'm continuing to buy this for as long as I can stand. The reason being that I don't think it's Giffen's and DeMatteis's fault that this is bad. There are obviously editorial changes since longtime collaborator Kevin Maguire was fired from the book last minute. And you can tell that a lot of the first issue was written for him. There's a two page spread of 18 panels (not sure if that technically qualifies as a spread) of dialog and facial closeups.
Also the plot should be a lot funnier: The wonder twins (Terri and Terry) clone the Justice League with DNA stolen from Cadmus. Although they fuck up and the clones are brain damaged and their powers don't all work right. Also, Batman and Superman bicker a lot.
This is classic Giffen and DeMatteis humor and it all falls way flat. What keeps me holding out hope is that DC did not want both Justice League and Justice League Europe to be humorous, and within a year or two of each series, they turned full vaudeville and bwa ha ha. I'm also happy to see that Howard Porter is not penciling issue five. He's still on the series as far as I know but at least he can't do more than four consecutive issues even with lead time. I'm not sure what kind of terms Magure left under, but maybe they'll get him back on at some point.
What you should get instead if you don't want to wait it out like me (And you don't have to. I'll update if JL3000 gets better) is Larfleeze. Giffen and DeMatteis with Scott Kollins (and sometimes Giffen) on art. Though not their best work, this is classic dialog and snappy humor. This is my favorite DC book right now (although I am only reading three and I hate one of them). Very enjoyable.
