For most readers, we hit a point in our reading where we pause and go "This book reminds me of "__X__" book. Or even the point where every book of a certain genre (or more often sub-genre) that every book just blends with another book.
Some popular examples are vampire novels and their over-the-top popularity explosion after the Twilight novels. OR dystopian books after the Hunger Games (and now Divergent). I have heard from so many readers that they are burnt out of an genre or saying that the books are too similar and not original.
I think we all get burnt out of certain types of books once in a while. Sometimes very specific (such as just avoiding a particular author or maybe just not into vampire romance, etc), and other times more broad (no more horror or fantasy or YA) might sum it up better. My thing is to break away before it starts to effect your opinion of the books. If you start to feel things are too similar or dull or over-used, etc change directions. Pick up something completely different. Maybe even break away from your comfort zone of reading.
Also the more you read of a specific type of book, the more alike they can often seem. If you have read a hundred Urban Fantasy novels then it is very easy to say it is sounding like another book. But it doesn't mean it is the same. For many authors, to write in a genre they have probably read their share that is already there. So yes some elements may have stuck in their head and come out through their own writings. And even if it is not, with all the books, movies, etc out there, it is nearly impossible to have a completely original idea. Someone, somewhere probably did something similar.
I did a project with a group of 5th graders, to write a pirate story. Between 2-4 pages long handwritten. That is the only instruction they were given. After sharing them all, many of them had similar themes or character types to at least 1 or 2 other stories in the group of 14 kids. So if that can happen in a small group, imagine what can happen when there are hundreds to thousands writing the same genre or theme! Similarities can and will happen.
For some readers, they like the similarities. Be it their comfort zone or they like to compare and contrast the stories. Others get "burnt out" very easily. I am somewhere in between. When reading a book I can often find similarities to another book. I like to focus on what makes the book original. Are the characters unique or have some creative tick about them? What about the relationships or the setting in which they live? And once in a while I do get genre burnout. All that means is time to change paces for awhile. Sometimes a subtle shift like YA paranormal to Adult paranormal and other times a complete change is needed. I feel it is better to do that than trudge through book after book all the while feeling that I have been here before with the last 10+ books.
What about you? Ever suffer from this and if so what do you do. What do you think or do with books that remind you of another book?
