Positive: Good CGI, enough to make it a barely believable background and action scenes, but not great. Loosely based (meaning embellished for entertainment purposes) on post WWII varying factions vying for power in China as Japanese occupiers were being driven out.
Neutral: Interesting tie in with contemporary descendant revisiting and re-imagining that period. Acting, dialogue, script, filming, all acceptable and pretty standard, straightforward, but nothing jumps out as being incredible. It almost felt as if it was a Communist Party sponsored politically correct promotional film. Rather than being a serious historical docudrama it seemed more like a lighthearted fantasy story.
Negative: If looking for historical accuracy, then other than someone infiltrating a gang to spy with some sort of positive outcome for his efforts, it came across as an imaginative fantasy which may be all that a viewer is interested in. Misleading cover art.
