The montage at the beginning

I was just wondering what other viewers thought about it. After viewing the film a few times I realized the point of the opening, or at least what I think is the point. To see most of the main characters struggling with modern technology like vending machines, ticket dispensers, metal detectors, etc., I think it's supposed to help set the mood for the characters' desire to escape to a time when these things didn't exist. Prudie's embarrassing experience with a store metal detector was particularly amusing.

Also, I think Grigg rides his bike, rather than driving his car, because film adaptations of Jane Austen's novels often show men traveling on horseback, rather than using a carriage.

I haven't read the novel, so perhaps these things were mentioned there...I don't know.
