Howling II is directed by Phillipe Mora, rather than Joe Dante who directed the first film. I'm having difficulty finding actual reviews of Mora's films, but from what I see he is generally known for terrible, low-budget b-movies. To be fair, Joe Dante came from a background with the king of the b-movie, Roger Corman, so this isn't a huge knock against Mora. Also interestingly, Gary Brandner, the guy who wrote the Howling trilogy of novels, co-wrote the screenplay for this entry. This is actually kind of strange since it apparently has nothing to do with the novels, and so I'm not sure how much actual input he had on it. This becomes even stranger because apparently Brandner didn't like the first Howling simply because it diverged from the plot of his novel. In terms of the cast, the movie features 2 notables: Christopher freaking Lee (who is as awesome as he always is) and cult favourite, Sybil Danning (whose... uh... "performance" is sure not to disappoint her "fans").
I can't find any budget numbers for this movie, but it's pretty clear that it probably had less than the rather modest $1 million which the original Howling had... either that, or the production crew wasted far more of it, which is a distinct possibility, since they managed to wrangle Christopher Lee and shot about half of the film on location in Soviet-controlled Czechoslovakia. Whatever the case may be, compared to the first movie, the special effects look like ass. Check out the "werewolves":
