Metacritic reviews

Teen Wolf is a clever and inventive film, a soft and contemporary retelling of the familiar werewolf tale.

The formulae of gal-next-door and big game are followed so slavishly that it's hard to laugh at Teen Wolf even on the rare moments when it is original. The script and the direction are simply too lazy, too contemptuous even of adolescent audiences. [24 Aug 1985, p.C5]

Fox's performance is a shadow of his "Future" self, and the rest of the cast -- everyone from teeny-boppers to wise guys to baffled adults -- are equally benumbed. You really can't blame them, what with a screenplay by Joseph Loeb III and Matthew Weisman that relies on "losing control of his bodily functions" for its biggest laugh. [24 Aug 1985, p.C6]

For a film that's so innocuous, Teen Wolf is aggressively boring.

Lightweight item is innocuous and well-intentioned but terribly feeble, another example of a decent idea yielding the least imaginative results conceivable.
