Just finished Kirkman's run on Ultimate X-Men. I know it's very criticized by fans but I kinda enjoyed it? The final arc was bad, but I liked the build-up with the alt-Outback X-Men a lot. It's nothing spectacular, of course, but at least he tried to do new things with the concept - Millar's run was alright, Bendis' run was very... Bendis-y, Vaughan's was a lot of meandering teen drama... I guess I was just not a fan of the series in general.
