This question asks whether a film, TV or stage version of a book is always weaker than the book it came from, and you discuss how true that 'never as good' claim is.

The claim assumes original and adaptation chase the same effect on the same audience, so the adaptation can only fall short of a fixed target, when each medium has its own strengths and the source is not always the better work.
degree: adaptations usually lose something the source did best, but 'never as effective' overreaches, because effectiveness is medium-specific and some adaptations surpass forgettable originals.
How to approach it. Test the absolute 'never' against the question of what 'effective' means, since a film and a novel pursue different effects and an adaptation can do things the original cannot.
An adaptation tends to be less effective than its source when the source's power lies in what only prose can do, interiority, ambiguity and the reader's own imagining; but the 'never' collapses where the new medium supplies effects the page cannot, so the honest position is that adaptations usually lose one kind of power and gain another, not that they always come second.
An adaptation arrives carrying the source's reputation and its readers' expectations, so it competes on ground already mapped by the book, and the deepest, most personal works do tend to lose in translation. But this confuses 'judged against the original' with 'less effective than the original': the adaptation is measured against the book unfairly, by a standard that ignores what the new medium adds, and once that standard is corrected the absolute cannot hold.
Adaptations usually surrender the source's most private powers, and for the devoted reader the book often stays supreme; but 'never as effective' mistakes a tendency for a law, since effectiveness belongs to the medium and the better-made work, not to whichever came first.
The question is built on a false contest, because an adaptation is not a copy competing with an original but a translation into a different language of effects, so asking whether it is 'as effective' is like asking whether a poem is as effective as the painting it describes; they are different works, and the right question is whether the adaptation is good, not whether it beats its source.
Readers leave the cinema saying the book was better, and they are not making a category error; they are reporting a real loss of something they valued. The reframe must not deny that experience. But the verdict 'the book was better' is a judgement about this adaptation's craft, not proof that adaptation can never be as effective, and the same audiences just as often prefer the film of a book they found dull, which only a craft account, not a seniority law, can explain.
Adaptation is translation, not competition, and the question's 'never' rests on a quiet prejudice that the page is the real work; judged honestly, an adaptation can match or surpass its source or fall short of it, and which one happens is settled by craft in the new medium, not by the accident of which version came first.
Option A accepts the comparison and calibrates by degree, granting the source's private powers while showing the medium can win and weak originals get surpassed. Option B rejects the comparison itself, arguing adaptation is translation into a different medium so 'as effective as the original' is a category error driven by pro-prose bias. Both are defensible: A is the measured Discuss answer a marker expects; B is the premise-rejecting move that scores higher if the translation frame is held without dodging the real audience experience.
