For example, if you write about domestic affection and social isolation, you can write about how you see this theme in the novel, how it appears in the 1931 film, how Young Frankenstein treats this theme. You may or may not find that this theme is addressed in the review you wish to include. If it is, then you may simply write about it. If it is not, then you should respond to the reviewer's assessment of Frankenstein. (Because it is general in nature, it would be best to put this paragraph right after the introduction or the paragraph on the Frankenstein novel.)
Keep in mind the purposes of the introduction--to introduce your argument, not summarize the paper--and conclusion--to give the reader a sense of your argument's significance by restating (not repeating) your thesis and showing why it matters. You may find materials on the University of Pennsylvania Electronic Edition of Frankenstein helpful to you. (Click on "Contents" and then go to either "Characters" or "Themes.")
