Started out great. I liked the unfolding mystery, mood and cinematography... but the story gradually felt like it was running out of gas, and limped to a lackluster, anticlimactic and somewhat predictable end.
And the end... so hard to relate to Ralph walking around that cave in the dark without his gun drawn. Felt like I was watching actors try and make it dramatic, instead of being drawn into the story by the acting.
Also, ten episodes could have been condensed into a much more exciting six.
