This movie is entertaining, but suffers in that the producers took a two minute idea and stretched it out to full movie length. The expansion allows to better flesh out a cast of characters, but suffers in that they 'show' far too much of the monster, detracting from its effectiveness. That being said, the expanded running time allows the filmmakers to explore the haunting elements within as an allegory for dark depression. This is a deeper movie than its blueprint, though never dwelling too long on the psychological aspects, instead more content to create a tense thrill-ride. While the ending could seem unsatisfying to many, I feel it works. This is certainly a movie I can recommend, but I'd recommend the short much more. The short: B+ The film:
