I think one thing that keeps a film relevant is its message. You can have a strong cast, director, writer, and crew, but when the lights come up and the movie has ended, you hope it leaves a strong enough impression that keeps you thinking about it. It also helps if the film’s message coincides with something going on in society at the time, and that’s what we get here with Suffragette.
How often nowadays are we told that this it’s the year of the woman? Where are the strong female protagonists? I’d argue that we have films like that, but there’s been a lot of discussion about assertive female characters on screen. We get a look here at one with Thomas Vinterberg’s “Far from the Madding Crowd,” an adaptation of Thomas Hardy’s 1874 novel and the third time, to my knowledge, that this story has been turned into a film.
