I was wondering if there was some practical, legalese reason for this "pushback." It seems that whenever someone tries to faithfully deliver on some other artist's vision, the original artist's foundation or estate or representatives will always chime in to say something like "Well, we disavow this work and it has nothing to do with the actual artist!" No matter how much love, care, and attention to detail in the derivative work. Happens a lot when a movie is based on a book. The adaptation is never good enough.
