I haven't seen that one, but I've been watching the Ken Burns documentary recently. It seems suitably fair. Where maybe some of the proposed "McNamara Fallacy" breaks down from OP, according to archives that they go through in the documentary he knew his approach wasn't working for a long time, he just did not (or would not, or could not, depending on your perspective) say so publicly and didn't seem to have any other way to measure progress.
