This film is based on the book by Gillian Flynn, and oddly enough she wrote the screen play. Hopefully, you will read the book and skip the movie.
The book was good because it was suspenseful, the movie is not. The book was good because a major portion of it was from the main characters perspective, Amy, through her journal. The movie left most of this out. The book was good because the husband, Nick, had a minor role, not so in the movie. Ben Affleck plays Nick and was probably the worse choice for the part. The book has his mistress constantly bugging him about their relationship, the movie left this out. In the book, Amy’s parents are extremely weird, not so much in the movie. In the book the tension is immense when Amy is robbed at the cabin she is staying in, the movie falls flat on this point.
The fact that Flynn wrote the screenplay confuses me because you would think she would want the film to honor the book, it does not. This one gets one cigar and again, if you haven’t seen the film, skip it, just read the book.
