Question (Spoiler)
I liked the film quite a bit. It's a long way from say, Cabin in the Woods, as an outstanding example of its genre--still, I liked that they could go about in daytime, but still had to be invited in to a dwelling.
One problem: the Brotherhood's intransigence re: women. Sure, they go way, way back, well prior to the Industrial Revolution & beginning of women's emancipation. & some, like Savella, go back even further, plus he's apparently an old soldier, used to the company of men.
Still, in order to survive the Brotherhood must change with the times: they're not still walking around in Medieval or Napoleanic Era garb, after all. & it's clear that women can create, so why not start letting them?
Further, (& I haven't researched this, I admit), don't Irish/Gaelic legends usually portray women in a more substantial role than say Norse or other Continental-based sagas?
Seemed odd is all.
Then there was Ruthven. A Royal Navy captain. He goes to the island with Darvell. He enters the shrine to find Darvell's body, but is not himself transformed. Years pass, & Darvell returns to give Ruthven the map. But now that Ruthven sees what the shrine can do, why does he even need the map? An ordinary person might forget how to locate the island, but a retired seaman?
Furthermore, & even more nitpicky, if the boatman who bring them there won't step foot on its soil, then they must have some idea of its significance, & they surely need no map to find it. So just find the boatmen, & they'll find the island for you.
Yeah, too much time on my hands.
But a fine movie & interesting spin on the genre, all in all.
Ps: After watching this & say, True Blood, does anyone else wonder if vampires wouldn't be able to save home buyers money & possible litigation by performing title searches ... just ask the right person to invite you in. If it works, the title's sound:)
