Was there anything weird about the way Frankenstein was written?

Mary Shelley wrote _Frankenstein_ in epistolary form, which is a literary technique that presents the story as a series of letters or journal entries. This was an unusual way to write a novel at the time, and it gives _Frankenstein_ a unique and personal feel. Additionally, Shelley uses nested narratives, with characters telling stories within the main story, which adds to the complexity of the novel.
