Frank Manchel’s Criticism of “Broken Arrow” Film

Does it make sense for historians, such as Frank Manchel, to make an extended case criticizing “Broken Arrow”?

Given that we have few historical films today, and also considering arguments for and against challenging films on historical grounds, would you argue that it makes sense for historians, such as Frank Manchel, to make an extended case criticizing “Broken Arrow” for what he views as its failure to get the “facts” straight about Cochise and the Apache groups of Arizona in the second half of the 19th century?
