Marianne on the other hand is Elinor's opposite. I don't like Marianne's explosive, emotional, and showy characteristics. She's the type of person who'd follow her heart and emotions before anything else. But, she seem to value Elinor's opinion a lot, and vice versa. Marianne allows her emotions to cloud her judgement. For example, by choosing the younger and philandering Willoughby over the honorable Colonel Brandon. Well, of course, Marianne doesn't know that at that time.
In this novel, Jane Austen portrays two different characters. The "sense" and the "sensible." I think she was trying to teach balance - that women can be both sense and sensible. In the end, Marianne and Elinor have their happy ending, but I think that's because both characters have truly supported each other; teaching each other that both characters can come to a middle ground.
This weekend, I'll be watching the movie as well. Happy reading!
