Me and this book have been on bad terms ever since Kyle & Yost took over. I didn't have any problems with X-23/Laura joining the book, since I figured no one can butcher her worse than Claremont did in that "On Ice" arc of Uncanny. In fact, I rather liked the "Childhood's End" arc. When this arc started, the bus explosion and funeral were handled very well. In fact, the main characters have all been handled very well.
Problem is, only the main characters have been handled well. Wallflower was given the shaft, Icarus degenerated into a pile of un-winged crap, and Wind Dancer just disappeared completely. If you didn't make it into the main cast after Yost & Kyle took over, good luck surviving long enough to be a background character.
I actually threatened to drop this book, until "Crusade"'s ending. It wasn't bad. I'm a little upset that Cannonball gets treated like crap every other year, and that a member of the Guthrie clan is gone, but like I said before-- the main cast of this book is handled well.
The pointless deaths of supporting characters had better end, though. Otherwise, I'm dropping this book like a bad habit. Going from a mutant Harry Potter knockoff to having a bodycount larger than a Rambo film doesn't sit well with me.
