Picked up the DVD yesterday. I hadn't yet read the book when I saw it in the theater back in April, so initially I didn't think it was too bad, most likely because they crammed about 400 page of material into 90 minutes, so there was a lot to take in. Watching it a second time (and knowing what's coming next), the acting is often pretty hammy, and the production values are kinda cheap. The music is pretty great, though. I'm normally not a fan of that Spielberg-esque "tell me what I'm supposed to feel" style of musical scoring, but here it worked. Biggest complaint, they showed Galt over and over.

I only spot-listened to the commentary track, which was recorded in August. Interesting that they could only get the two producers and the screenwriter to participate. Not even Paul Johansson (the director) was there, and he even played Galt. They didn't seem to have much to say about the movie production, instead spending most of their conversation talking about how Ayn Rand has been wrongfully classified as a rightwing ideologue. They also said that pre-production for Part II should begin by the end of this year; and that Part II will include D'Anconia's "money is the root of all good" speech.
