You can just hear the passion that Oliver Stone has for this project (i speak of Alexander, not just the Directors Edit)
This solo commentary covers a great deal of the history of Alexander The Great, the making of the film itself. And also deals with aspects of the backlash the film suffered (wrongly in my opion...the film is a good movie and didnt deserve the flack)
What interests me in this particular commentary are the comments about this Directors Edit, why certain scenes are longer, why some oare shorter, and why some have been relocated to totally different sections of the movie. . . . . Recommended for Oliver Stone fans.

Stone touches upon the challenges of bringing Alexander’s life to the big screen. Much of what we know was learned third hand by scholars who read texts long lost by people who knew the man. The director also addresses much of the criticism leveled at the movie (i.e. the heightened dialogue which he explains was a homage to the old Cecil B. DeMille’s classic, Biblical epics). As his typcial with all of his commentaries Stone speaks candidly, although on this one he goes after the critics in this excellent track.

An awesome commentary track, interesting from beginning to end. I burned this commentary track in iTunes, and this was my most listened-to mp3 for quite some time. My only criticism is the mix volume when there are gaps and silences in the commentary, I wish they would keep the movie audio track subdued all the way through, instead of having it jump abruptly to the foreground, which makes for an annoying and irritating listening experience. "The Doors" deals with overall mix and gaps the correct way.

The bits where historian Robin Lane Fox talks in the previous commentary are not in this track, so Mr. Stone talks in these bits. These are the only bits that are different from the Theatrical Cut's track. Otherwise, it's the same track. I'll say what I said in the other review. Mr. Stone talks about the history, Alexander, some of the more technical aspects of, say, the battles. One thing he talks about here why he structured the movie the way it is now. The information is very nice, though if you've heard the theatrical cut’s commentary, there's no real reason to listen to this track. It's a very nice track, but kind of laid back.

This is a great commentary by Oliver Stone on the directors cut edition. He gives a lot of details about the story and the way he chose to do certain scenes. Though I agree with "Jchgf" above, the audio is pretty inconsistent. Overall, a great addition to anyone who liked or loved this movie.

I gave it an 8 even though it is closer to a 7.5. A lot of other reviews on here got it right. What I would add is that Stone goes into some detail about the historical questions, and why he chose to show the versions he did. (For instance, I did not realize watching the film either time that Ptolemy (Anthony Hopkins) poisoned Alexander.)

And I like that he talks about the known historical inaccuracies, and why he chose to compress some battles together or move things in time, so that he could get all of what he wanted to say about Alexander in a film under 3 hours long.

There is also some good talking about (but not a lot of it) why he chose to show Alexander personal life in such detail, as he knows it was very important to describe the man, and not just his accomplishments like most other stories on him.
