I'm glad Wolverine isn't used too much in AXM.
It reminds me of how it used to be, he always was a very cool character, but he never got that much face-time to begin with; he was there to do what the other X-Men couldn't and provided a bit of cynical, comic relief.
In AXM he does exactly this, for once he's not the focus of the book and is much more of a team-player, I still enjoy having him there though just because he gives some of the best one liners and he really completes a very memorable X-Men line-up.
To say Whedon has been mischaracterizing him is criminal.
