They are. Edits in comic books could range from color adjustments to reworking dialogues or adding/removing panels to better suit the overall theme and flow.
Well, for copy editing a novel, you need to focus on language accuracy. That means correcting punctuation, fixing word usage, and ensuring the sentences are structured properly. Another important aspect is to maintain the author's voice while improving the clarity and flow of the text.
You could also rewrite the dialogue. Instead of having characters express their sadness in a very direct and gloomy way, make them more reserved or use euphemisms. For instance, instead of 'I'm so heartbroken', they could say 'There's a heaviness in my heart'. This can make the scene less intense in terms of sadness.
A great sad anime story often has strong character development. For example, in 'A Silent Voice', Shoya's journey from a bully to someone seeking redemption is really moving. His relationship with Shoko, a deaf girl he once bullied, is full of complex emotions. When you see how they both grow and the pain they go through, it makes the story very sad and also very powerful.
Another great one is 'Clannad: After Story'. It shows the life of Tomoya Okazaki after high school. He has to face many difficulties in life, including the loss of his wife Nagisa during childbirth. The story is extremely sad as it portrays the harshness of life and the importance of family. It really tugs at your heartstrings.
The author's edits in novels are important for several reasons. Firstly, they can correct mistakes like grammar or continuity issues. Secondly, through edits, the author can adjust the pacing of the story. A slow - paced part might be tightened up to keep the reader's interest. Edits are a way to polish the overall work.
