Hard to say. I used to use this structure as my bible but I felt some of the comparisons I was getting back were very simplistic. Basically some students were only pointing out obvious similarities but failing to comment on subtle differences between the texts. As long as you bear in mind that subtle differences matter every bit as much as similarities, you should be fine to use this structure. This example might also help (it’s cultural context rather than theme but the same basic principles apply) http:///2013/12/sample-comparative-link/
This interactive guide provides an introduction to the basic characteristics and resources that are typically used when students compose comparison and contrast essays. The Comparison and Contrast Guide includes an overview, definitions and examples. The Organizing a Paper section includes details on whole-to-whole (block), point-by-point, and similarities-to-differences structures. In addition, the Guide explains how graphic organizers are used for comparison and contrast, provides tips for using transitions between ideas in comparison and contrast essays, and includes a checklist, which matches an accompanying rubric .
