Well, it could be many things. Maybe the writing is just really bad, like full of grammar and spelling mistakes. Or perhaps the author completely misinterprets the characters from the Zelda series, making them act out of character. Another reason could be that the plot is really convoluted and doesn't make any sense in the context of the Zelda universe.
One reason could be really poor writing skills. For example, if the grammar and spelling are constantly wrong, it makes the reading experience very difficult. Also, when the plot doesn't make any sense at all, like characters suddenly changing their personalities without any good reason, or the story going in completely illogical directions. Another aspect could be a lack of originality. If it's just a copy of other popular fanfics with no unique elements added, it can be considered awful.
One reason is that they don't match the child's age group. A story that's too advanced in terms of themes or language for a young child is going to be awful. For example, a story about complex political intrigue isn't suitable for a preschooler. Also, if the story is too preachy, trying too hard to teach a lesson in a really obvious and dull way, it can be bad. And if the illustrations, if there are any, are really ugly or disturbing, that can also make the bedtime story awful.
Stories about monsters that are too scary for kids, like a monster that lives under the bed and always tries to grab the child's feet when they sleep. Another could be a story with a sad ending, such as a little puppy that gets lost forever in a dark forest and never finds its way home. Also, stories full of mean characters who are constantly unkind to others without any redemption.
An 'awful Harry Potter fanfiction' might be one that blatantly plagiarizes other works. Instead of coming up with original ideas, it just steals plots or character arcs from other fanfictions or even from non - Potter related works. Poorly developed relationships can also be a factor. If the romantic relationships seem forced or don't have any build - up, it can make the whole story feel off. For instance, if Ginny and Harry are suddenly in love without any real interaction or development of their feelings. Additionally, if the fanfiction tries too hard to be edgy or different by including elements that are completely out of place in the Harry Potter universe, like modern - day technology that has no place in Hogwarts, it can turn out to be awful.
Well, without more context, it's hard to say exactly. 'Joan is Awful' could be a story where Joan is a character who exhibits awful behavior. Maybe she's mean to others, like constantly gossiping or being unkind to her neighbors. It could also be a story where she gets involved in some sort of unethical or immoral situation, such as cheating in a competition or lying to get what she wants.
Awful supernatural fanfiction often has inconsistent world - building. The rules of the supernatural world are not clearly defined or are constantly changing throughout the story. Plot holes are also common. You might find things like a character suddenly having a new power without any explanation. And sometimes the dialogue is just cringe - worthy, either too cheesy or completely unnatural.
One characteristic could be poor writing quality. Maybe the grammar and spelling are all over the place. For example, sentences might be jumbled or words misused.
Well, without more context, it's hard to say precisely. 'Miss Awful' could be an unlikable character in the short story, and the story might revolve around her actions and how they affect others. Maybe she has some awful traits like being mean - but this is just speculation.
