The Wein/Adams Batman story is one of the all time best.

Besides the fact it was Adams (nuff said), the story actually had something of a scientific basis for the Werewolf. Lupus, was essentially a mutant (though the story didn't call him that), who was created by a scientist's genetic tampering. And, rather than being dispatched with silver or wolfsbane, he was defeated by good old fashioned science, in the form of electricity.

It stands as probably the best example of how to do a classic "monster" story in the world of a semi-realistic character like Batman, avoiding the need to shoehorn him into the world of mysticism and superstition.

I've never it seen it, but I think the Dini-Timm animated series adapted it too.
