Great Acting and Directing but plot holes

Rating: 7/10 (16 October 2014)

Gone Girl was a thought provoking thrill ride that was quite enjoyable but falls apart when closely examined.
The performances by Affleck, Pike and Coon were spot on; from the very first scene they were believable. Affleck immediately became "Nick." However Harris's performance was not! I have seen that performance by him many times before.
The directing was great; Fincher did a great job of not revealing any of many twists and turn that movie takes. I was sucked in emotionally from the start. At times it was difficult to understand the dialog; I think a sound editing problem.
The reason I gave it 7 out of 10 was the major plot holes, which I believe was the writing. For example, Amy purchasing the Craig's list car, Amy making the "tip" about the woodshed, Amy's drive home covered in blood...also as the movie progressed the police became more and more inept closing in on Keystone Cops levels.
Despite writing problems, I recommend seeing Gone Girl just for outstanding acting performances
