Frankenstein is a romantic novel because it embodies many of the characteristics of Romantic literature. The novel explores the power of nature, which is a central theme in Romanticism. The descriptions of the natural world are detailed and often used to mirror the emotions of the characters. For example, the stormy nights can be seen as a reflection of the turmoil in Victor's mind. Moreover, the concept of the 'noble savage' is also present in the form of the monster. Initially, the monster is pure and has good intentions, but society's rejection turns him into a vengeful being. This exploration of the relationship between nature, society, and the individual is a hallmark of Romantic novels.
Well, Frankenstein is a romantic novel in several ways. For one, it has a fascination with the sublime, like the desolate Arctic landscapes where much of the story takes place. Also, the characters are often in touch with their intense feelings. The protagonist, Victor Frankenstein, is driven by his passion for knowledge and creation, which is very much in line with the Romantic idea of the individual's pursuit of something grand and all - consuming.
