Even this seems like oversimplifying it, because it removes all of the hedging he did prior to dropping the bomb. Removed from the context, it comes off as bitter.
Well, I think he has every right to be bitter. If someone made a universally-acclaimed movie in which I was portrayed as a complete jerk (or even a slightly different type of jerk from the jerk I really am) then I'd be annoyed about it too.
in his own words, the movie is "a complete work of fiction."
which removes the need for the brackets.
