Warriors of the Rainbow: Seediq Bale Part I Blu-ray [Hong Kong]

Eventhough this movie is getting a USA theatrical release, I think it will be two parts shortened into one film, sort of like what they did when Red Cliff was released in USA theaters. I don't want to see any hacking, so i'm just going to buy these releases instead of waiting for the USA blu-ray release.
 
Is this a good movie? i dont think ive ever seen an asian film that dealt with Indian Ancestry.

It's supposed to be pretty good, especially for a big-budget Taiwanese film. They say the action gets a bit tiring and overkill...I'm still thinking about buying it or not. I read online that it may play as two versions in the USA - cut shorter version and two-part 4 hour version.
