The Unseen is the debut feature film from special effects artist Geoff Redknap, which gives an interesting take on the invisible man story. Bob's slow transformation is shown in graphic detail, as it appears that he is missing large chunks of his body. This adds a supernatural twist to what is both a crime thriller and a father/daughter drama. In fact, Bob trying to make amends with his estranged daughter Eva makes up the main emotional core of the film, especially since it seems that Eva has inherited Bob's condition.
The Unseen isn't really a film that can easily classified under a single drama. While there is a bit of a body horror element to Bob's condition, the story is much more of a crime thriller, especially as Bob is forced to assist the crooked drug dealer Crisby. At the same time, there is the drama of Bob reuniting with his daughter after a long absence, which adds a bit of double meaning to the title of The Unseen. Altogether, The Unseen turns out to be a somewhat touching twist on the invisible man story.
