how to start compare contrast essay?
i have to write a compare contrast essay over the movie and novel The curious case of Benjamin Button but i have to compare and contrast the exposition in them…i am having such a hard time starting this HELP

Try and go for something using the words… “although” or “while”.. Although the novel (lesser comparison) was an intriguing scene for the mind, The Curious Case of Benjamin Button film was far greater in (adjectives that really express the movie), (strong verb i.e. encouraging) the audience to view the movie <-- Make these last words the significance of your comparison. This is basically a thesis that could help set up your main points. Of course, you shouldn't use this word for word, but the structure idea is effective. Good luck.
