I read the book. I saw the movie. I enjoyed it a lot.
I felt that the film's screenplay was fairly true to both the original story and Rand's philosophies in general.
The acting was very good. A couple roles were played by some of my fave American character actors.
The direction felt rushed or incomplete. Certain scenes were less than perfect. But they shot it in 6 weeks with only a couple days of advance planning. Very little rehearsing etc. They claim to have shot 10 takes per scene.
The worst thing was the editing. A lot of bad cuts. Made it feel like a made-for-TV drama to me at times. Supposedly they spent a long time in post production, not sure why it felt so jagged to me.
I'm looking forward to parts 2 & 3.
