Pros: The plot had a purpose. It was mysterious and revealed itself at a good pace. The payoff was pretty good too.
Cons (numerous): Why do writers think that annoying characters make the story more compelling, especially when their annoyance is due to stupid behavior. This isn't really a spoiler, but the group is in a very remote town far from home and packing up for the next destination when one is missing. The pissed off character who knows the other one got on a train for home says, "I don't know where she is, how should I know". Does this idiot realize none of them are going anywhere until the other person is accounted for? That is the most idiotic reaction with zero upside. If he would have held out not telling the others, like the childish infant he was acting like, they'd be stuck in that town for weeks looking for her. That isn't compelling writing for an emotional character, that's dumb. Also, early on, some of the characters are so annoyed with each other I was thinking why would this group that apparently hates each other plan a vacation together? If they would have smoothed out the rough edges (idiotic ones) it could have been a satisfying low-budget movie.
