Patrick Martin said:which means that being "transparent" doesn't actually refer to the outcome or the result at all. It isn't even the first or last movie that lacks a tangible resolution.
But this one doesn't have any real payoff; it feels like watching someone's mundane daily commute where you just randomly curse people out in traffic, knowing you'll be doing the exact same thing tomorrow.
I didn't really grasp the point of the film, even though, to be fair, it was visually stunning (if nothing else, I enjoyed that aspect). If she had wanted to escape, she could have done it a million times over because the island isn't quite that isolated (I mean, even within the film itself, there are characters from other places—for instance, through education, since she speaks and understands a foreign language, though I doubt she was homeschooled, or through work, given she made it past 17, etc., etc.).
POSSIBLE SPOILERS
For instance, at the beginning, I was somewhat convinced that she was actually the daughter of a foreigner and that the whole plot was hidden there. Then, toward the end, I found myself almost rooting for the girl to end up in a pit (the tide) and that the actual ending was just her final fantasy. If nothing else, I was cheering for her to finally strike her father in that closing scene and swim right out of the frame...But then, once the credits finally rolled and I saw it was a female director/writer, things started to make more sense to me—clearer, I suppose, in the sense of why they were unclear to me in the first place. 😁
