Re: Best Marvel comics of the past 10 years
That is the Whedon arc of Astonishing. I would caution that it's mainly worth it for the Cassaday art. The new Hellfire Club bit is pretty cool, but the other two arcs are as forgettable as any X-Men arc (even though something "important" happens, it probably ought not have).
I agree with the assessment. Other than perhaps the first storyline, there is really nothing groundbreaking to the Whedon X-Men. After the first arc it's mostly standard science-fiction stuff that other writers have already done with the team.
Lex Luthor is a true American hero.
