All together now; let's all do the reviewer's cheer: "Why bother if you can't do it right?" This applies to almost any scenario, but especially that stale chestnut, the teacher/student encounter. Brando's "method" is madness: ad-libbed dialogue, which produces equally disastrous results as recitations of the written word.
Aside from a total lack of theatrical panache (not to mention an even semi-convincing set) Naughty Bookworms hardly makes up the slack in its highly perfunctory sex scenes. Oral exams (especially from Thorn) provide minor thrills, but from the look on Annie Cruz's face while getting cornholed, she may as well have been doing calculus.
Tech specs are just as low, especially the ragged editing. The most arousing desktop dalliance features Faith - and that was helmed by guest director Vince Vega! Even graded on a curve, these students of adult education receive a generous C minus.
Retailing: Staci Thorn completists may want a look.
