I liked it, but....[spoilers]
1) Mainly they're rescued by others, so wouldn't it have been fairly obvious how they survived? I mean, a soccer team stranded via plane crash in wilderness? Isn't cannibalism almost a cliche? Surely the authorities were bound to investigate the deaths of those that didn't come back.
2) The plane. A bit ridiculous, but not a bad concept. Yet how does it have a full tank? Surely whoever flew it there used some gas. I went back & looked. I assumed a fuel leak caught the bear on fire, but no, it was the bear. It just caught fire. If sabotaged, by whom? Misty seemed as shocked as anyone else. Was it some supernatural force that didn't want them to leave?
3) The fixer. I honestly thought she was dead from the get go & Misty just imagined talking to her. How does she stay so clean after days in captivity? No bathroom breaks? Surely she could take Misty physically, so I don't buy Misty temporarily unlocking her & keeping her under control. And why not doctor the cigarettes & put them back in her purse? Suppose she didn't want to smoke cigs that had been in the trash & decided to buy new ones ... where's Misty then?
Finally, we're shown that the girl being hunted & killed wore a heart necklace similar to Jackie's. I don't think there's any way Jackie isn't dead (yet there's precedent with Van coming back from the wolf attack), so how does fresh meat have Jackie's necklace? You'd think Shauna would naturally inherit it, but she clearly wasn't eaten.
Best thing: Melanie Lynskey
