Good or Bad doesn't apply to Bendis' UXM. Good or Bad doesn't apply to Morrison's run. Good or Bad is mostly just useful for runs that are kinda just 'bad' and therefore easily split into such simplistic categorization.
Good runs are sometimes necessarily bad.
Art that 'means' something doesn't mean much to me.
Bendis' UXM was a character driven soap opera that focused its attention deliberately on condensed episodic damage and in the soot and confusion of aftermath. Knowingly or unknowingly it grounded itself in the uncomfortable nothing place of after the End. Xavier is dead. The Phoenix infused hyper idealism of who the X-Men were and strived to be has tragically and utterly come to a permeant conclusion.
IMO, Bendis attempted and succeeded in expressing grief, trauma, brokenness and real life relatable humanity. It's something so rare in X-books since, well, it's rare in super hero comics in general and it's something Bendis does so well. I take for granted how his storytelling permeates, I often don't notice how he manages to instill in me a deeper empathy and appreciation for characters and stories and ideas I think I know...he actually makes me laugh, brings tears to my eyes.
UXM made me feel things. I didn't have to work at it. I didn't have to think about it.
Also, the art by Anka and Bachalo is incredible.
I really treasure Bendis' UXM and even appreciate the 'difficulty' and honest failure of ANXM which somehow managed to hold onto to this harsh enduring idealism as a living youthful presence reminding and viscerally keeping the broken immediate from collapse with the pressure of a hope precariously there in the midst a wreckage their future selves not only come to see as separate from themselves, but as the very new beginnings from which they must take in order to grow. It's difficult. It's just life. And that's difficult, imperfect...it finds no resolutions, it revolts, it contradicts, it fights impossible odds, and those odds are sometimes itself...life is response it just responds and strives and occasionally stops doing anything or saying anything...it simply takes a breath and then back into the ordinary uncanny gutter of stars through the drainage bars.
And that's Bendis' UXM to me.
