re: Harry Potter movies and JK Rowling plagiarized Young Sherlock Holmes (1985)

So your title says JK Rowling rips off some 1985 movie then in your post you link the similarities of the movie and the first Harry Potter Movie then elaborate how Chris Columbus was the director/producer link. Hmmmmm I'm still wondering how JK Rowling wrote a 7 book best seller and created a unique, deep, and rich magical world yet because the first movie is similar to this 85 Sherlock and that both involved Columbus, her entire literary and I'll say it again, literary works are a rip off?
