It's just 3 hours of playing "Who's that in disguise?".

Rating: 5/10 (5 March 2013)

Right from the start you play the game of trying to identify who the famous actor is underneath all the prosthetics - "Ooh that's Tom Hank" or "Is that really Hugh Grant?" or "Can that possibly be Halle Berry?" etc etc. All this disguising of nationality, race and gender is all very clever, but unfortunately it's just self indulgence on the actors' parts and gets in the way of listening to what they are saying.
That is assuming you could even understand what they're saying in the first place. The language on the Big Island is a prime example, which appears at the very beginning and sets the tone of unintelligible mishmash for the rest of the film. And if your movie is going to be so complicated in its telling, then you really should do us all a favour and make it easy to understand what's being said. Yet another example of directors assuming that because they know what they're actors are saying then we all will - you only know because you told them what to say in the first place!
Having mentioned the prosthetics, I also have to call into question the quality of the make up - especially in Neo Seoul, where the attempts to make Western actors look Far Eastern was laughable - almost as laughable as the attempt to make Doona Bae looked Western by giving her red hair and freckles.
So, on top of distracting disguises, poor make-up and indecipherable dialogue, then you have the problem of telling 6 stories in parallel. This means we never get the time to invest any emotion into the plight of the characters (possibly with the exception of Sonmi~451) so really I didn't care what happened to them. Ewing? Didn't care. Frobisher? Didn't care. Rey? Didn't care. Cavendish? Didn't care - and anyway what was the point of this element of the story?
I have just read the plot overview on Wikipedia and can tell that either the directors cut bits out of the movie or the problems with spoken language made it impossible to pick up on certain aspects that MAY have made this a more enjoyable movie.
In conclusion, nearly 3 hours of butt numbing, sleep inducing, self indulgent multiple role playing with no regard for the audience.
Oh and finally, Susan Sarandon's teeth in the Big Island! They're all living in straw huts with no technology or medicine and yet Susan Sarandon's got the most amazingly white teeth! Do directors actually look at what they directing?
