See, I'm with you on Morrison in this way: He is, arguably, one of the top idea men who have ever written a comic book. But that's where it goes with me -- he has ideas, but far too often, I haven't seen him execute them, give them a real foundation.
The good thing about it is that talented writers -- far more often than we, as readers, give them credit, probably -- can take those ideas and make them "live."
Fantomex was pretty much just a concept, a few ideas thrown together. But Remender has given him substance, a foundation, and made him interesting.
He deserved better, Fantomex did. (What? Is that another spoiler?)
