Son James made a very similar “target audience” fail remark during the previews about different movies at our location as well.
James has read the book three times and I read it once then listened to the unabridged audio version once (yes, Galt’s eight hour monologue actually takes eight hours). We both liked the movie but had some minor criticisms about the movie skipping over some points too rapidly for “newcomers” to really understand the points being made.
We both really liked that the sex scene with Dagny was not the way Rand always portrayed an ideal man/woman relationship.
The scene wife Barbara liked best was where the guy wanted Rearden’s money but asked Rearden’s name not associated with the donation.
I agree with the commenters who said the casting of James Taggert was a little off.
I was uncomfortable with a train going 250 MPH on those curves with the passengers standing up. Sorry, but I don’t think they ran the numbers through the physics equations before they filmed those scenes. And the curves had better have some appropriate slope to them to keep the train from rolling over or pushing the tracks off the railway bed.
