As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or specific expertise, but this question will likely solicit debate, arguments, polling, or extended discussion.
Example of a question that is bad for this reason:
Did Bob Dylan deserve his Nobel Prize?
This question is likely to solicit extended debate rather than fact-based answers.
This can be "converted" to a significantly better question:
Why did the award committee decide to award Bob Dylan a Nobel Prize?
Note that this second question is related to the first question, but it's possible to answer this question by appealing to facts (rather than merely offering personal opinions).
Opinion-based questions can often be edited to become related, fact-based questions (such as the one above).
One test for whether a question is excessively opinion-based is: "What kind of evidence could someone supply for (or against) a particular answer?" If you can't clearly answer that question, the question is probably not fact-based.
Good answers should appeal to specific facts, references, and specific expertise to defend them, not merely cite personal opinions. These facts can include quotes from relevant passages of the work, quotes from the author, facts that provide historical context, etc.
To improve answers that were downvoted for this reason, consider adding relevant quotes or facts that support your opinion.
Also, consider providing credible sources to back up factual claims. Lack of adequate sourcing is a very common reason that people downvote answers.
