OK so first things first the sound is a bit dodgy, but persevere because the screen crackles with tension. The writing is good and the filming style doesn't disappoint. It's suitably dark, and no one, not even out our heroine Mary Yellen, looks pretty in that vapid way that some costume dramas enjoy. She's a bit grubby, but still attractive, so she seems more realistic, because she isn't portrayed like Anne of Green Shipwrecks. The locations are treated like another character in the story. The acting is exciting, with huge amounts of magnetism. Each character has an interesting back story that is sometimes hinted at, sometimes explained. The thing I noticed first is that everyone is dirty, their hands, their hair, their clothes, and of they would be. Smuggling is a dirty business, this production lets you see just how dangerous and desperate it is.
