I have so many thoughts and feelings about this film, I don't know where to start! I'll divide my review by the six different parts of the overall story:
The Pacific Journal of Adam Ewing: My least favourite part of the novel as it's rather dull, but made a lot better in the movie by 1) it being Jim Sturgess (<3) 2) it really being rather short and to the point. The final scene with the father-in-law was also more poignant by flicking back and forth between that and the Sonmi story.
Letters from Zedelghem: Why of why did this story get entirely rewritten for the movie?!?! For one in doesn't actually take part in Zedelghem anymore but Edinburgh instead (which doesn't really make sense as Vivian's wife still has a Dutch name), and two they completely changed the reason why Frobisher at the end [spoiler]kills himself.[/spoiler] And even though the viewer sees what happened to the second half of Ewing's journals, I don't think Frobisher actually finds it in the end? Such a shame. Having said that, Ben Wishaw was astonishing in the role and really made me love the character much more than I did in the novel. And Sixsmith just broke my heart.
Half-Lives: The First Luisa Rey Mystery: One of my two favourite parts of the novel and still very good in the film. Again there were some changes I do not understand (why they omitted the locker scene for instance as well as the evil Hugh Grant character b*ying out Luisa's magazine to fire her) but the essence remained. It is a shame they didn't reveal the importance of the rapport until the end of the story as I can understand why viewers would be confused by this. LOVED how they included Javier's voice to provide the "mystery" part of the title and also implied he wrote the manuscript that landed on Timothy Cavendish's desk, which I don't recall happens in the novel.
The Ghastly Ordeal of Timothy Cavendish: A rather dull and seemingly insignificant part of the book (in comparison to the other stories at least) made a million times better in the film. Provided some much needed laughs between tense scenes (I'm still giggling when thinking about "pussy") and had a really sweet ending.
An Orison of Sonmi~451: My absolutely favourite part of the story. So complex and so f**ked up. I'm really disappointed they omitted at least half of the story which explains much more how that particular time period was put together and the immense impact that the changing of this one particular fabricant had on society (and how special she really was and how she became that special). We didn't even get to see any other fabricants that looked completely different from Sonmi (there are some really cool ones) and they also completely ignored the major mindfuck at the end of the story which reveals that in actual fact there is no [spoiler]rebellious Union, but this was all just set up by the current government to create a fake enemy that will ensure that fabricants will remain "slaves" but that she knew this all along and that by standing up for what she believes in and telling the people she's already changing their minds.[/spoiler]FYI Jim Sturgess makes for a very hot Asian!
Sloosha's Crossin' an' Ev'rythin' After: This part is really creepy and more more so in the book than in the film, particularly the tribesmen (though they did go a bit overboard with "Old Geordie" int he film). I personally loved the language used and got used to it quite easily (it's the same in the novel). In fact it reminded me that all 6 parts had their own distinctive voice, which unfortunately didn't come across as much on screen as it did in writing. Maybe I missed it, but in the film did they ever explain WHY Meronym was staying with the villagers? Because I don't think they do though it's told in the book. Also, I have no idea why this wasn't [spoiler]set on earth[/spoiler] as I thought it was in the novel? (in fact they mention Hawaii in the novel which is supposedly where the fabricants in
An Orison of Sonmi~451 go after they receive their 12 stars.
It's a shame so many people got confused by the use of the same actor for different roles and the not too clear connection between the characters [spoiler](which is the comet shaped birth mark on the 6 main characters).[/spoiler] I think having read the book and being able to fill in any missing gaps (and know instantly who the characters were without having to get used to them) really helped me to just focus on the magnificence of this enormously ambitious film which spans different genres and times giving each one a distinct feel and look (which also explains why there were multiple directors as they each had their own specialities). Also, the actors were extraordinary in all their parts (I didn't even spot all of their "versions", so it's well worth waiting for the credits to see what roles each actor portrayed) though Hugo Weaving in the nursing home was a bit too ridiculous and may have distracted the viewer away from the story.
I personally think the movie could've been improved by:
1) Not going back and forth between the various story arcs so much. The book tells the stories in two parts each and in chronological order (with the middle bit about Zachry being told in a single part) which makes it much more clear.
2) Split the story into at least 2 movies. This would open up more time to spend on the individual stories to explain eg. the Luisa Rey rapport and the Sonmi revolution and not just focus on how everything is connected and actions ripple through time.
Overall, 9.5/10 - amazing, but not perfect and it certainly stays with you, which is quite an achievement nowadays.
