For the first half-hour, this movie is fine. Acting is OK, scenery is beautiful. Then it gets boring. Then it gets ridiculous, showing (presumably) hallucinations. Then it gets even more boring with more hallucinations. Similarly, the music starts off OK, but rapidly becomes annoying. Because it's based on a true story, somebody has to survive to tell the tale, so you can guess the ending, and I ended up being pretty uninterested. Not bad, but not worth watching twice (and possibly not even once!).
