Enormously Flawed Storyline

Rating: 5/10 (18 March 2015)

I didn't hate this film as so many others have. But as pointed out by many, the plot holes are major... however, let's start with the PREMISE, which is deeply flawed.
A woman is going to fake her own death, goes to all the trouble of drawing a pint or two of blood from herself, among many other actions. BUT, her writing treasure hunt clues?? Why would anyone write treasure hunt clues -- that she knows and intends for the police to find? This is a flashing billboard saying "I'm alive"! Not only that, the police could test for her fingerprints on the paper; even at one point, the detective takes one of the envelopes from Affleck gingerly with 2 fingers, indicating the "delicacy" of potential prints. Yet the police NEVER comment upon whether the wife's prints (or anyone's prints) are on the notes. If the wife's prints are on the notes, then the wife is gone but alive somewhere. Follow the logic?
And there is no way that a man (Affleck) who wants to kill his wife, is going to write treasure hunt clues -- that then indicate his wife is alive -- yet continue to incriminate himself by WHERE they are placed. NO one would do this. Therefore, the logical deduction is that the wife is alive. And all the police have to do is test for prints on those notes -- which they never do as it's never brought up. If they did, the movie would be over 5 minutes after it started.
All the other massive plot holes seem to be covered pretty were in other reviews here.
One other thing: I also cannot buy that because the wife sees her husband on TV pleading for her to come home and that he loves her, that this is ENOUGH motivation for her to actually commit a very gruesome murder herself. This is not logical or believable on any reasonable level. Particularly when she did *nothing* to stop or fight back just 20 minutes earlier to the people who robbed her of money stash -- that was providing her with the ability to carry out this whole scheme. Asking us to believe she's been "pushed" or motivated to slashing a person's throat - - even if she is crazy -- this simply was not believable. It would have been more believable for her to knife her robbers 20 minutes earlier.
I did like a number of the actors, and much of the dialogue. Just wish it had been a better storyline overall. As talented as the director is, I am a bit surprised Fincher accepted/agreed to this script.
