This British horror cop-buddy movie is a cliche, done much better with the series FOREVER KNIGHT. A hotshot young detective is assigned to a new partner, who is notorious for 'getting the job done'. But he soon learns that his partner isn't entirely human-he was brought back to life by this type of parasite that feeds on people. It takes form of his hand clawing and this morey eel type mouth opening on the palm of his hand.Because we never see how this guy was before he was taken over by a monster we don't see any change in the character. He acts exactly the same. Which, I suppose, may be the point of the movie. Nevertheless, I had the feeling that I've seen this all before-and seen it done much better. A very forgettable film.
