Sanditon has received a turbulent and unstable perception, some stating that the work is some of the best ever written, whilst others believe Austen had not only grown old but a bit slow whilst writing the last work she would ever write. Considering - probably, according to her other works - less than a quarter of the book was written, as well as being unedited, these critics are understandable.
Sanditon is very different than the other books Austen has written in the regards to it not being comedic nor romantic. It might have been planned to become one of her traditional best-selling books, as we do not know her writing process. Austen might have put the comedy into her novels after writing the plot itself. At the end of the book, it is also clear that there is a slight hint of a romantic story blooming.
Charlotte finally notices a man she finds handsome, and a romantic relationship might have bloomed between them, had Austen just had a little more time left to write. However, they never reached having a proper introduction or getting to know each other, considering that only 25 thousand words were written in the manuscript. During that time, however, Charlotte grew as a person and character; from a child living with her parents to a woman in control of her own life.
