Lee McCoy’s review published on Letterboxd:
Road horror films usually strike my fancy pretty well, but originality doesn't come along that often in the subgenre. Alone doesn't have shock value, but it makes up for it in the character decision making dept.
Our main character is calculated in choosing the most logical course of action, and STILL succumbs to the danger. Marc Menchaca (remember this name) really makes a mark as the persistent stalker. I've seen 2 instances of his work (this and The Outsider), and the guy steals every scene.
The real clincher for Alone is the ending, which might be one of the most satisfying of the year.
