The first rule of Gone Girl Club, you never talk about (how average) Gone Girl is.

Rating: 5/10 (5 October 2014)

I am pretty sure that I fall in to the minority here, but this really didn't grip me. I will also go as far as saying that this is one of Fincher's Weakest films.
The casting was for me, totally weird, but maybe that's personal, Ben Affleck basically can't act, the leading lady, whom I honestly can't be bother to look up, is generally annoying in all her roles and here becomes really rather annoying (not in a good way). While the 'guy' from How I met your mother, is one the most openly gay men in America so I find him in his role hard to swallow.
Meandering and dull, with enough product placement throughout to burn my eyes out (you probably didn't notice, but there is rather a lot). With some simply ridiculous moments (why would she be sent home from the hospital absolutely still covered in blood, for dramatic effect?).
There is little or no invention in this film and the whole thing is drenched in Cliché. While it (the plot) was absolutely obvious from the start. My feeling is that this is written by an inexperienced screenwriter, and as this is her only screen play to date, I don't think that this is too far off the mark.
I thought that I love Fincher for much of his other work and I always look forward to his work because it is synonymous with invention and twisting the boundaries of cinema. But when I look back at his work, there is really only Fight Club, Seven and The Game, which did anything really special (for me), I liked Benjamin Button and I liked Zodiac, but nothing great. For me Fincher has to get back to what he did great at one point instead of resting on his laurels. For me this is a money making film and not great cinema that I would expect from him. But then again, why not make a sure thing, a sure way, for sure money, than risk it all in being actually original.
But like I say, I am maybe in the minority, this is simply my opinion.
