Granted, it's part of the film, but the mother is insufferable. She listens to, very literally, nothing her daughter says to her. When the daughter speaks, the mother just rolls over her with her own dialogue.
She is very duplicitous with her daughter and it would annoy any parent watching this.
Yes, it is part of the plot but it was hard to watch. I wanted her to die off in the movie. Right up until the end she was a moron.
As for production, they did crash in Canada. On their way to Alaska, but the story has them crash in Canada.
Did they not glance at maps? Yellowknife is in the opposite direction to Alaska. No one would travel in that direction to get there. I could not identify the plane but it was small, and likely only able to make an 800 mile trip and the distance from their take off location in Washington state up to Alaska would be roughly 1700 miles. More stupidity.
We do not have state police, nor do we have the FBI. We have the RCMP; wow, how the moron force was strong in these people.
We do not have Park Rangers in american uniforms. We have Conservation Officers in their own uniforms.
We do not conduct search and rescues like they represented in the movies. I doubt the US does either for that matter.
Overall some production errors were tolerable, but some were just unacceptably bad. A lot of American movies get made up here, and if the story is supposed to be in the US they will use their names for things, but when they are actually set in Canada for the story line, get it right. Don't be so dumb.
Overall I do not recommend this film and that is based on the insufferable mother character and how the actress portrays her with showing all her emotions on the face, when she should have a poker face so as to survive among killers. Bad writing.
