This is an almost entirely single-handed, dialogue free, story of a woman who is taking (very basic) climate and wildlife data on an otherwise uninhabited island off the Cornish Coast. Clearly this has been a mining island in days gone by, with ruins and mine-workings strewn around the place and those exude a sort of creepiness that is only augmented by the constant wind and the sound of the waves crashing against the rocks. Her days are routine, to say the least, but gradually we start to realise that the island has been touched by tragedy - as has the woman (Mary Woodvine) herself. Auteur Mark Jenkin doesn't rush with this, but rather takes his time to slowly but surely allow us to put together some of the pieces of just what drew this woman to this isolated and lonely spot. It's that repetitive pacelessness that I struggled with. We see the same shots over and over again, the same procedures and scenarios and though there is a very incremental development of the plot, the whole thing just doesn't really move. It has the hallmarks of an original "Poldark" episode married with the "Dr. Who - Stones of Blood" series from 1978. To be fair, it has a very authentic 1973 feel to it, and the audio mixing coupled with some sparingly used visual effects do help create a very slight air of mystery and tragedy, but I found it all just a bit lacking. Worth a watch though, but I'm not sure I will watch it again.
