I rented this film and then before I watched it I saw the review ratings, and absolutely dreaded the thought of wasting two hours on this film. I therefore ignored the film for a day and I have just watched it. By the four stars I have given I can conclude that this film is actually pretty good.
At no moment in the film did I lose interest and the story, directing and characters were engaging and the plot was interesting and at some points genuinely chilling and dramatic. It was a
film that I therefore enjoyed. I think the setting and flair of the film is very much in the mould of LA Confidential and Chinatown.
I could not give the film five stars because the film really is quite difficult to follow at times. My advice to anyone intending to watch the film is this is a really good film but pay attention and try to remember the names of the characters. It is extremely difficult to follow the plot precisely and I think a second viewing would be helpful, but in the end the story fits nicely, and even if you don't quite follow what is going on the directing, music and acting is nevertheless compelling.
I think that a different reason why the film has received bad reviews on this site is because the film is based on a book, and normally a person who has experienced one form of media on the story ends up disliking the new media. I have not read the book and I won't because of the above reasoning, but I think that for anyone who has not read the book I really can't see how if with a little attention this film cannot impress.
