With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: Whedon was involved in an advisory role early in the production but departed after becoming dissatisfied with the direction the film was taking. Executives at 20th Century Fox removed many of Whedon's jokes, believing the humor to be too abstract for audiences. The executives also rejected the darkest themes in Whedon's initial script, since they wanted to make a breezier comedy. Merrick's suicide was replaced with his being killed by Lothos, and Buffy's burning down her high school gym to kill all the vampires was eliminated altogether.
text_B: Could you draw the conclusion that while Whedon's efforts were appreciated, the network executives simply had to face the reality that it is very difficult to market a comedy to the public?
NO.
