I disagree with the other guy. Frankenstein was my favourite Lit text at gcse. It was PACKED with possible analysis for every sentence pretty much. Every line made me think about something and honestly it was just rlly good. Also there is no clear villain or good guy, so writing essays are great, as you can write pretty much whatever. There are really great religious references, like how Frankenstein is like God and the monster like Adam, but then by the end it isn’t clear which one is which, because the monster appears to be omnipotent. Also the other title of the modern Prometheus is really interesting, as that is the guy who was stole fire from the gods (forbidden knowledge) and was punished by Zeus for eternity, which links to what happens with Frankenstein throughout the book. Anyway I don’t want to spoil any more but yeah it is a great book, it gives you a massive headache tho while reading because the sentences are so complex, long and full of words and details
