Watched the new remastered blu-ray and love the cleaned up movie.
You can really see it in the transformation scene.
This and the Howling are the best werewolf movies in my opinion.
We follow David and his friend/ Jack, as they are backpacking across England. One night, they are attacked by an animal. David is injured, but Jack is killed.
As David recovers in the hospital, he has werewolf-themed dreams and sees a mangled Jack visit him. Jack tells him that David has become a werewolf and needs to die so that Jack and other victims can pass on.
David does not believe this and thinks the visit from Jack is a hallucination. Until the night of the full moon.
