I saw this at the San Francisco Independent Film Festival and liked it a lot. It worked for me as a slightly weird comedy, because I don't like horror, but there were only a couple of minutes I had to close my eyes.
The dialog was good, the costumes and settings were not far off BBC-quality, which is amazing for an indie film. I liked the way the plot twists and even meanders, it kept surprising me in good ways. I even warmed up to the Willy Grimes character, who I quite disliked at the beginning. It would have been better if there'd been any motivation for the woman to be so interested in going to the island: that felt very much like a plot device.
I am fond of Dominic Monaghan, and he did a good job at pratfalls, horror, and at the more thoughtful moments. Nice voice in the narration, too.
This would be a fun and unusual date movie.
