This is not a good film, however I am going to try to be objective. It is based on The Malay Chronicles from the 16th Century, which are pretty much myth and if you approach this as a sort of swords and sandals `Sinbad' then from certain viewer's points of view this may have some merit.
It supposedly tells the story of the uniting of the Han Chinese Empire and the Roman Empire of Hadrian, a Roman `Prince' is sent to marry a Chinese `Princess' and they are to meet in Malaysia via Goa, where the hapless Romans have to enlist the aid of a sea rover (Merong Mahawangsa) who claims to be descended from Alexander the Great. Once they get to this place of the `joining of empires' and a 'great trading centre'(a beach with a few bits of bamboo) where this ceremony is to take place, things start to go wrong.
If you have stuck with it thus far there is then a big fight, which is basically what this movie is selling itself as, a fight fest. I don't want to spoil the `plot' but needless to say after many, many plot holes there is some more fight scenes. I watched this with my nephew and one of his friends and they thought it was `awesome' etc. I begged to differ citing the historical, factual, material and language inaccuracies, all to no avail. That I think is the point, if you are prepared to suspend belief and forget even basic historical knowledge, then there is an average fight fest type of film trying to get out. The cover does mention the special effects as `stunning' well to have believed that you probably would needed to have been `stunned' possibly with a taser.
Also there really is not a `clash of empires'; more like a fight over some rock in the Pacific Ocean, so pretty much setting itself up for a fall straight away. It was to be called `The Malay Chronicles' which would have been more honest, but we all know that war sells. Also the sleeve claims that Alexander the great was `a renowned naval captain and traveller...' There was me thinking he was a sort of Emporer, General and looked like Colin Farrel, glad they put me straight.
The CGI is quite good in places, but the speeded up action scenes are a missed opportunity, the acting is wooden to faux melodrama and the sets are a bit `make do and mend'. The de rigueur man on man combat does go on interminably; I am always amazed that in a battle where everyone is `tooled up' that the two main protagonists decide to go for a bit of martial arts fisty cuffs, just stab him already. At 107 minutes this did seem like a chore, but it does have an audience, I just think with a 15 rating they have accidentally excluded most of them.
