This reminds me of...
For some reason this movie reminded me of Gone Girl. I'm not a fan of the movie especially because it's a fictionalized story of a real person. Why not just write a movie about some random person or, since it is fiction, why not come up with a much more interesting story; perhaps something similar to her own works?
Had the same story been the true story of what really happened to Mrs. Christie during her eleven day disappearance I probably would have enjoyed it more. As it is a piece of fiction, it's wasn't worth the effort.
Woman, man! That's the way it should be Tarzan. [Tarzan and his mate]
