How do I make a NPC's head look at the Player?

I tried using this script;

Character = game.Workspace:WaitForChild("MRbraveDragon")
wait(1)
while wait()do
	script.Parent.Head.Neck.C0 = CFrame.new(script.Parent.Head.Neck.C0.Position, Character.Head.Position)
end

But it didn't work... I know it has something to do with the NPC's rotation but I'm not quite sure how to fix that. Does anyone know how I would go about doing this?
