It can bring the story to a wider audience. Many people who might not be inclined to read a novel would be interested in watching an anime. It also gives a new life to the story, with the added visual and auditory elements enhancing the overall experience. For example, the music and voice acting in the anime can add more emotion to the story.
One challenge is condensing the complex plot of the novel. Novels often have detailed storylines and many sub - plots, but anime has limited time to present all these elements. Another challenge is character design. The anime needs to accurately represent the characters as described in the novel in terms of appearance and personality. Also, staying true to the tone and theme of the novel can be difficult. For example, if the novel has a very dark and gritty tone, the anime has to convey that through its visuals, music, and voice acting without losing its essence.
Well, it varies. Some anime comics are very loyal to the source, while others might make significant changes to fit the animation style or story pacing.
The consistency depends. In some cases, the anime sticks closely to the manga, but in others, there might be changes in plot or character development for various reasons like animation style or time constraints.
The Naruto anime is widely regarded as a faithful representation of the manga. It manages to capture the key elements and excitement of the original. Although there are some differences to accommodate the medium of animation, they don't significantly impact the overall experience for fans of the manga.
