For me it is still The Howling. Perfect blend of humor and scares, IMHO. And biped werewolves, you have to have biped werewolves
I like Werewolf in a Women's Prison a lot, though I don't much care for Eyes of the werewolf (that one was too much bottom of the barrel for me). Quite liked Audie & the Wolf too (probably because the premisse of a wolf turning into a man during the full moon reminded me so much of the novel Howling Mad, though they're two totally different stories).
