I've seen this movie long time ago and I only remember bits and pieces of this movie. I remember few scenes from the movie and before explaining the scenes I'd like to tell that it might be a B - movie, poor CGI and might be a low rated movie.
Few scenes I remember.
Scene 1 - Lead(male) goes into a tunnel or a cave with is very dark and gets exposed to some sort of light(appear like a sunshine) and turns into a werewolf.
After he becomes a werewolf, he starts killing people( without being aware of) and turns into a man and he starts seeing dead people(probably the ones he killed.).
Scene 2 - Lead sees as dead woman with scars on her face and body and while she sneezes, her eye falls down on the ground with cord attached and she tries to put back her eye along with the cord.
Scene 3 - Lead lady friend(probably know that lead is a werewolf) put some meat pieces into a blender and grinds it and put the juice in a glass and gives it to lead(I don't remember whether he drinks it or not) and she sits astride on the lead while he's laying on the bed and she removes her top and places both palms of the lead on her bare breasts and talks something.
Scene 4 - Lead and his lady friend fight with some guys underground and remember the lady has a torch(not electrical) in her hand and they kiss and tries to take off their cloths.
Scene 5(climax scene) - (the climax scene is shot in the subway(a train car)) In the train a bad guy starts beating the lead repeatedly and lead gets angry and turns into a werewolf and the bad guy falls down on his stomach and lead runs his claws on the bad guy's back and tears him apart.
That's all I remember.
