May have finally finished this short film review, though a small voice says not. Belying the review's length is the three hours it took to write and edit.
Despite Snowpiercer's unsatisfying ending, the film is worth seeing. Sensitive viewers are warned, though, about the stomach-churning violence.
Details about the film's development, production, and release are on Snowpiercer's Wikipedia page. The page includes a summary of the plot, so readers may wish to skip that section if, like me, they prefer not to know a film's narrative before watching it.
