Frankenstein has inspired dozens of film adaptations, from the 1931 Universal classic to more recent, more textually faithful versions, and comparing the novel to one or more of these adaptations is a popular and genuinely engaging assignment. It also invites a specific set of grading challenges around what counts as a fair, well-supported comparison rather than simple preference for one version over another.

The most common weak essay in this category amounts to a list of differences between the novel and the film, such as noting that the famous "it's alive" line does not appear in Shelley's text, without analyzing why those differences matter or what they reveal about how each medium handles the novel's core concerns.

A rubric for this essay type should require that every noted difference connect to a specific analytical claim, such as arguing that a film's choice to portray the creature as inarticulate, in contrast to the novel's eloquent, self-aware creature, fundamentally changes how the story handles questions of sympathy and moral responsibility.

It also matters which adaptation students are working from, since the 1931 Universal film differs enormously from more recent adaptations in its treatment of the creature, its handling of Victor's motivations, and its overall tone. A rubric should account for this by requiring students to specify which adaptation they are discussing and to ground claims about that adaptation in specific scenes.

Grading for Analysis of Medium, Not Just Plot Differences

The strongest film comparison essays often move beyond plot differences into questions of medium, asking how film's reliance on visual and auditory storytelling changes what the story can accomplish compared to Shelley's dense, introspective prose. This is a genuinely sophisticated move, and rewarding it explicitly in the rubric encourages students to think about adaptation as a creative and interpretive act, not simply a faithful or unfaithful retelling.

• Every noted difference between novel and film connected to a specific analytical claim
• Clear identification of which specific film adaptation is being discussed
• Evidence drawn from specific scenes in both the novel and the film
• Consideration of how the medium itself, not just plot choices, shapes the story
• A thesis that makes a claim about what the comparison reveals, not just that differences exist

Handling the "The Book Is Better" Default

Many students default to arguing that the novel is superior to its film adaptations, sometimes without fully engaging with what the film accomplishes on its own terms. This is a legitimate position but, like any thesis, requires genuine textual and cinematic evidence to earn a strong score, rather than functioning as an assumed starting point that does not need defending.

Rewarding essays that engage seriously with what a film adaptation does well, even while ultimately arguing for the novel's greater complexity, tends to produce more balanced and more credible analysis than essays that dismiss the film adaptation from the outset.

Common Factual Errors in Film Comparison Essays

Because popular culture's image of Frankenstein's creature, green skin, flat head, neck bolts, comes almost entirely from film rather than the novel, students sometimes misattribute these visual details to Shelley's original text when describing the source material. Watching for this specific conflation when grading helps catch a factual error that can otherwise slip past unnoticed in an otherwise well-argued essay.

Addressing this conflation directly in feedback, rather than simply marking it wrong, offers a genuinely interesting teaching moment about how adaptations can come to define popular perception of a text more powerfully than the original itself.

Structuring the Rubric for Fair Comparison Across Different Films

If students are permitted to choose from multiple film adaptations for the same assignment, the rubric needs to be flexible enough to apply fairly regardless of which film a student selects, while still holding every essay to the same standard of textual and cinematic evidence. Building the rubric around analytical skill rather than any single film's specific content keeps this comparison fair across a class with varied choices.

This flexibility is worth the extra rubric design time, since allowing student choice in adaptation tends to produce more genuine engagement than assigning every student the same film regardless of interest or prior familiarity.
