A Film With So Many Plot holes

Rating: 5/10 (1 June 2015)

It could have been the best movie of 2014. The direction was great (David Fincher's name is enough), acting was great and the atmosphere was brilliant. This movie was heading in the right direction, but then they decided to ruin it. It is full of plot holes that even a child can notice. I think most of the people didn't notice them because either they were shocked or they were mesmerized by Rosamund Pike. Lets talk about the things that did not make any sense i.e; plot holes in Gone Girl.
::::SPOILERS:::::
1- She somehow convinced the police that the guy kidnapped her right and the police wont go there to check. ? There were cameras and when she entered the house with Desi, it must have been recorded. There must be the recording of first few days.
2- Why would the guy try to burn the diary in Ben's father's apartment and how does he know where his father lives ? It raises questions..
3- She says that she lost a lot of blood in the kidnapping process but the police didn't check for wounds. There must be wounds all over her body. (in real there aren't because she faked it)
4- she said that Desi kidnapped her . what if he was in his office or in a bar with some other guy. It will work as an alibi. She didn't even know where Desi was ..and the police didn't even check.
5- according to her, Desi kidnapped her and then cleans the blood off floor. It must have took 20-30 minutes but he couldn't wait 5 more minutes to see if the diary is completely burnt ?
6- She came home covered in blood, then they went to hospital but the hospital guys didn't wash the blood off her and she comes back home covered in blood ? WTF
7- Ben found the stuff in the woodshed, why didn't he move it if he knew it could raise questions? he knew that police will arrest him if they find it. If he wanted them to find it then why didn't he tell them about it.
8- She purchased the stuff with Ben's CC, god that is a lot of stuff, Nobody saw it when it got delivered? She hides it in Ben's sister's apartment and Ben's sister didn't notice?
9- There might be fingerprints on that stuff..They didn't even check.also who signed the receipt when it got delivered? It wasn't Ben.
10- A girl who is a complete psycho, tries to frame you for her murder, kills another guy in process by slitting his throat and you choose to live with her? What the F**k.
I am not saying that the movie was bad. Everything was good except these flaws and these are serious plot holes. I can not expect these kinds of flaws from a guy like David Fincher. If someone can explain these things, I might watch it again to clear my doubts. I have given it 5 stars because of brilliant acting and direction.
