This movie clearly had a massive budget and has impressive special effects consistent with that. However it lacks any emotion, any real plot development or context, and it was not possible to feel for any of the characters at all. Some of the plot lines iare just ridiculous for example the assertion of the group of men stuck in the hold of a 10,000kg leaking boat getting rid of one of the men on board would somehow be the crux of the boat staying afloat. Having a non-linear narrative is all very well, but in contrast to other movies like Memento there was no real set of threads to put together once all was done. Overall extraordinarily disappointing and and non engaging.
