A Cure for Plagiarism / Could it be Magic?

I saw a poster for A Cure for Wellness when Joe and I went to see xXx: Return of Xander Cage and immediately thought of The Road to Wellville, which was based on a book by  T. Coraghessan Boyle, whom I dearly love, so I guess it stuck in my mind. And this morning I was lured into some click bait and started looking at the list of 2017 movies that I must see provided by MSN, and faith and Begorrah if A Cure for Wellness didn't appear on slide 11 of 48 slides. So I read the synopsis, and here's a bit that caught my eye: "Mr. Lockhart, a young corporate executive sent to retrieve his CEO from a bizarre health spa in the Swiss Alps. As Lockhart slowly uncovers the mysteries of the "wellness center," he finds himself falling victim to the same strange illness plaguing its patients." (http://www.msn.com/en-us/movies/gallery/2017-movie-preview-47-must-see-blockbusters-comedies-and-more/ss-AAlC4eV?li=BBnb2gh&ocid=mailsignout#image=11)  Hmmm. That sounds a bit familiar.  Here's a bit from the Wikipedia page on the plot of Thomas Mann's The Magic Mountain: "[Hans] Castorp undertakes a journey to visit his tubercular cousin, Joachim Ziemssen, who is seeking a cure in a sanatorium in Davos, high up in the Swiss Alps. In the opening chapter, Hans is symbolically transported away from the familiar life and mundane obligations he has known, in what he later learns to call 'the flatlands', to the rarefied mountain air and introspective little world of the sanatorium. Castorp's departure from the sanatorium is repeatedly delayed by his failing health. What at first appears to be a minor bronchial infection with slight fever is diagnosed by the sanatorium's chief doctor and director, Hofrat Behrens, as symptoms of tuberculosis." (https://en.wikipedia.org/wiki/The_Magic_Mountain)  The director of A Cure for Wellness, Gore Verbinski, said in an interview on ign.com, "There's this book by Thomas Mann called The Magic Mountain which has a wonderful premise, which we're kind of inspired by." (http://www.ign.com/articles/2016/12/20/a-cure-for-wellness-or-a-cure-for-franchise-filmmaking) Ya think? I suppose that in the 21st century "kind of inspired by" is the equivalent of "appropriated the idea completely." That really irritates me. Mostly because I've been reading The Magic Mountain for a couple of months now and enjoying it immensely, and I'd like to see Mann get a little more credit for his work. Besides, The Magic Mountain would have been a much better movie title.
