All the 'B.S' aside, this is a 'B.S.' movie.
Yes, I have read the comments regarding the filmmaker's choice to leave the ending ambiguous. Sure, that is always their right, but that doesn't often translate into a good movie.
Imagine what the movie "Titanic" would have been if it had ended right at the point where the iceberg is sighted.
Imagine what "Avatar" would have been if there had not been the big battle scene.
Imagine what "Raiders of the Lost Ark" would have been if the movie ended when they started digging in the desert.
Imagine what "Hunger Games" would have been if it ended when she said she would take her little sister's place.
"Meek's Cutoff" is a failure in experimental film-making. It really is a lot like watching paint dry. Then, with the build-up to the end, it just ends. There is no resolution to anything. Did they all die the next day? Did they start to slaughter each ox for food and to drink the blood? Did they find water? Was the Columbia River right over the next set of hills?
Anything could have happened yet the filmmaker chose to let it all be in our imagination. While that may work for some movies, it doesn't work for this one. After watching patiently for almost 90 minutes the filmmaker owed us more.
