I didn't realise this was a Chinese made film until I started watching it - and scrambled for subtitles - I was pleased they were smart - when English was used, there were no subtitles, when Chinese dialogue, subtitles - that were easy to follow unlike some films of this type.
Acting - as good as anything you will get from Hollywood except for the very top tier of actors, but it is very good to see Chinese actors getting a chance at international aclaim. Jason Isaacs was great - and actor we do not see enough of in my humble opinion.
Cinemetography - very good, but when you look wat who was directing, its hardly surprising. This was as good as anything produced in Hollywood and deserves recognitions for this.
Special Effects - pretty decent for a disaster movie that the makers would know would never challenge blockbusters for revenue return, but they clearly spent a decent amount and came up with some decent graphics, so fair play to them. My only gripe would be the volcano itself - Yes, Mount Fuji and Mt Ranier have this stereotypical appearance, but it is exceptionally rare to find an island volcano with the type of cone they displayed - that could have been modelled better and more relalistic IMHO.
Story - pretty predicable, same old disaster movie plot line that was like Dante's Peak with younger cast in a more tropical setting - akin to Hawaii Five-O or maybe Jurassic Park.
Scientific accuracy - Its a film, I do not expect them to be spot on the money, however, China has some of the finest geophysicists and volcanologists in the world who are doing amazing work - would it have been so hard to seek their advice and really take this film to the next level - bit of a clue - No-one, and I mean no-one survives a pyro-clastic flow, even in a car - they are travelling at 200mph+ and have temperatures of at least 750°C (1382°F) - you are killed instantly because your insides likely explode as does your skull as the fluids boil - Also, they showed a flank eruption in one scene, then a few minutes later is was gone - had the aliens stolen it, they do not go away that quick - the explosion would be catastrophic. Lastly - lava really does not flow that fast unless it is downhill - which a lot wasn't - The fastest lava flow ever recorded occurred when the shield volcano Mount Nyiragongo, in the Democratic Republic of Congo, erupted on 10 January 1977. The lava, which burst through fissures on the volcano's flank, travelled at speeds of up to 37–62 mph (60–100 km/hr), but on flat ground they only flow at about 10mph (16km/hr) on average - some at meters per day - it all depends on the magma.
Look, if you are not a picky bugger like me and you like disaster movies - you will love this one, it is well worth a watch as it is a very pleasing film to watch, it does not get staid or boring, the story flow is good and showing how the film was made in the end credits is awesome.
