I've always wanted to draw She-Hulk for a couple reasons. Ever since the Single Green Female arc back in 2004, Her book, along with Deadpool, are a couple of the more fun and lighthearted mainstream super-hero books that I read. It was like, the took Ally McBeal set in the Marvel universe.
Which made me all the more depressed a little when I heard that it got cancelled
One of the specific reasons were that sales were being hurt by other artists featuring the character in their books (Jeff Loeb's "HULK" for example) and causing discrepancies and confusion for readers. Nice internal communication Marvel
But I don't feel bad, as is the circle of life in comics she'll get a new book soon enough.
