The Hound of the Baskervilles has been adapted for the screen many times, from the 1939 film to the 1959 Hammer version to a 2012 episode of the BBC series Sherlock. That history makes comparison essays a natural end-of-unit assignment. It also makes them a common source of lists of differences that never add up to an argument.

The best comparison essays ask why a change matters. A student who notes that a film adds an action scene has observed something. A student who explains what that scene does to the pacing, the suspense, or the character of Holmes has analyzed something.

Grading these essays means checking whether the student is making meaning from the differences. It also means checking for accuracy about both texts. Students sometimes claim that something happens in the book that only happens in the film, or the reverse.

The framework below helps with both. It keeps the essay focused on a few meaningful differences instead of an exhaustive inventory. It also gives you a fast way to check that the student actually read the novel.

What Good Comparison Looks Like

A good essay has a thesis about the relationship between the two versions, not just a list of changes. It selects a few differences that matter and explores them in depth. It draws on specific moments from the novel and specific scenes from the film.

• The thesis makes a claim about what the adaptation emphasizes, softens, or changes about the source
• Three or fewer differences are explored in depth rather than ten mentioned in passing
• Each difference is tied to an effect on tone, theme, character, or audience
• Evidence from the text is quoted or precisely described, and film evidence names the scene or shot
• The conclusion says what the comparison reveals about the story or about the medium

Fact-Checking the Source Text

Because many students have seen a film or a summary, some claims about the book will be wrong. Keep a short list of key plot points to verify quickly. If the student attributes something to Doyle that is not in the novel, note it and ask for revision.

This is also a useful check on reading. It tells you whether a student finished the novel or absorbed it secondhand. That matters for the rest of the unit.

Avoiding a Ranking Contest

Many students write that the book is better or the film is better. That claim is fine as a starting point, but it needs criteria. Ask what "better" means, and require students to name the qualities they are judging, such as suspense, character depth, or faithfulness.

Encourage them to consider what each medium can do well. A novel can hold Watson's inner thoughts, while a film can show the moor's scale. Essays that recognize these strengths usually feel more thoughtful.

Grading Consistently Across Media

Comparison essays vary widely in what they cover, which makes them tricky to grade evenly. A rubric with fixed criteria, applied through a tool like GraideMind and then reviewed by you, keeps the standards steady across a full class set. It also flags essays that never move beyond a list of differences.

Tell students in advance which adaptations are acceptable, or provide a short list. That avoids arguments about whether a loose adaptation counts. It also keeps the comparisons focused enough to grade well.
