What Buffalo Boys lacks in originality it makes up for in spirit. There’s a verve in Wiluan’s direction, a sense of joy shaping his approach to the tried and true familial vengeance hook.

Buffalo Boys isn’t terribly concerned with sweeping vistas or slow-burn character development. Its primary function is simply to entertain, which in practical action-movie terms means lots of brawling and lots of blood.

For the most part, Buffalo Boys is a decent folk tale, despite Lee and Wiluan's periodic application of "Game of Thrones"-style sensationalism.

All in all, this Eastern western is a jovial genre cocktail, but it’ll be more interesting to see if its director can bring greater nuance to whatever his next project turns out to be.

Leveraging highly polished production values evoking the Old West with detailed sets, authentic weapons and period costumes, Wiluan gets enough of the details right so that the genre’s typical characteristics blend fairly seamlessly with the Indonesian adventure yarn.
