If your point is that the negative reviews come from a desire to "get" Stone, you'd have to cite good evidence for it. Roger Ebert gave it a negative review for example, and no one can accuse him of having an anti-Stone agenda.
As with JFK, that makes me wonder why Stone even bothers to make movies based on real historical figures. He should stick with fiction to make his points.
According to James B, Stone's Alexander is "weak, indecisive, plagued by self-doubt, and obsessed", and a "sniveling whiner". Is that what you learned about him?
