An entertaining, but not memorable movie

Rating: 7/10 (27 April 2015)

This movie is based on the novel of the same name by Gillian Flynn. Having read the book, I looked forward to viewing the film. I was disappointed. Movies adapted from fictions tend to be not as good as the originals. This movie is no exception. It cuts so many details from the book that the movie seems to be much shorter and simpler than the fiction. As a result, I like the book a lot more than the movie.
The movie is about the marriage life of Nick (played by Ben Affleck) and Amy (Rosamund Pike). Amy disappeared on their fifth anniversary. All the circumstantial evidences point to Nick as the murderer. Was he the killer? The twisted plot around this question is the interesting part of the movie. However, the movie is too long (2.5 hours), unrealistic, and at time unreasonable. For example, what is the motivation for Amy to commit murder? The conclusion of the movie is as disappointed as the book's.
I didn't have any strong impression one way or another after sitting for two hours and a half watching the film. I didn't remember any particular scenes, nor pieces of music, nor dialogue.
Here are my general scoring. Plot: Average, confusing sometimes, 6/10. Acting: Ben Affleck - good, Rosamund Pike - Very good, 7/10 Cinematography: Good, 6.5/10 Music: nothing memorable, 6/10 Dialogue: good 7/10 Overall impression: Movie is too long. Average to good, boring, 6.5/10
