X-Fans generally loved Gillen, Carey, Spurrier, Asmus, Bunn and plenty of others. And even the more divise writers (Brubaker, Fraction, Bendis, Aaron, Remender, Wood, Hopeless, etc) still had their fans as well as their ups and downs with the larger fanbase.
I think the only writer who X-Fans almost universally reviled was Lemire.
Also you guys are really trading up by snagging Ewing. I'd kill to get him on an X-Book finally.
