Unrivaled is about what you would expect from a straight-to-video action flick. The story is neither original nor inspiring, the dialogue is weak, and the fight scenes are just good enough to keep the movie afloat.
The only thing that really stands out about the film is the quality directing by Warren Sonoda. Good film work, editing and great lighting make for some decent visuals. The fight choreagraphy doesn't stand out. You're mostly treated to stand-up punching, a few kicks, and virtually no ground work until the film's end. All of the fights are set against hard rock, which works perfectly for the soundtrack.
Hector Echavarria does a terrible acting job as aging cage fighter Ringo Duran. Not to mention it's odd watching a guy that would be a Welterweight in the UFC giving a beating to Light Heavyweights like Rashad Evans and Keith Jardine. Only three or four cast members have any real film experience, including Al Sapienza (Mikey Palmice in The Sopranos).
Conveniently, Ringo Duran's second job is at a strip club, so there's more than a good bit of nudity in the film. Jordan Madley is painfully hot as Ringo's love interest Kara, as is Ashleigh Hubbard as the poetry-spouting pole dancer Pepper. But despite the hot women and cage matches, the movie is still predictable and not that exciting. Give this one a rent before you decide on buying the DVD.
