Marketic It's no definitive masterpiece but it's damn close.

AnhartLinkin This story has more twists and turns than a second-rate soap opera.

Brendon Jones It’s fine. It's literally the definition of a fine movie. You’ve seen it before, you know every beat and outcome before the characters even do. Only question is how much escapism you’re looking for.

Nayan Gough A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

Woodyanders Rugged adventurer John Hamilton (a solid and likable performance by Michael Dudikoff) gets hired by a team of shady folks with assorted secret agendas to find a fabled lost city located in the Amazon. Things go awry when the search party stumbles across evil Nazi scientist Dr. Wolfgang Manteuffel (a nicely sinister portrayal by Robert Vaughn).Adequately directed in workmanlike fashion by the usually more competent and on the money Steve Carver (whose other much better films include "Big Bad Mama," "The Arena," "An Eye for an Eye," and "Lone Wolf McQuade"), with an often sluggish pace, an overly convoluted script by Andrew Deutsch and Edward Sampson that gets bogged down in rather tedious talk, and infrequent, but still decently staged action scenes, this one has all the essential ingredients -- Nazis, a band of scurvy pirates, a tribe of deadly cannibals, plenty of treacherous back-stabbing characters, and a few okay plot twists -- to qualify as a possible contender, but alas the fairly tepid execution fails to make all these promising elements cohere into an exciting and satisfying whole. Fortunately, a fine supporting cast of reliable veteran thespians ensures that this picture remains watchable: Donald Pleasence as the shifty Heinrich Spaatz, Herbert Lom as the corrupt Colonel Ricardo Diaz, and L.Q. Jones as grizzled old rascal Eddie Hiller. Moreover, there's yummy distaff eye candy in the fetching forms of Sarah Maur Thorp as the sweet Anna Blakesley, Cynthia Erland as Spaatz's sexy secretary Maria, and Foziah Davidson as the tough Dalia. Both Avraham Karpick's slick cinematography and Sasha Matson's moody score are up to par. An acceptable diversion.

Cristi_Ciopron Seen when I was 14, a pretty kid, this Dudikoff adventure flick seemed wildly responsive to my desires from an adventure outing. The result was that I began considering Dudikoff an impressive cult—actor, an impressive action—star, something I've never really felt about, say, Lamas. I passed this conviction on to my family as well—such that a movie like that one (In Her Defense ) where Dudikoff loves Mrs. Marlee Matlin was quite respected. I can say I imposed Dudikoff as an essential movie star in my family.I thought RIVER was ideally crafted. Generally, I delighted in such formula movies—the more they conformed to a pattern, the more I liked them—Nazis hidden in South America—how thought—provoking is this? I liked Dudikoff's adolescent, charming air, a strong and handsome lad.

bronsonskull72 Michael Dudikoff stars as John Hamilton a mercenary who fights off deadly tribes and a sadistic Nazi who is still continuing his work in the jungle in this deathly dull affair. Dudikoff is just woeful here while the rest of the cast that include Donald Pleasance and Robert Vaughn are wasted in their roles. Boredom is all that floats in this river.

MarcCarpenter This is the worst film ever and as waste of time, money and life as I watched painfully throughout the whole of film what I thought was a jungle action adventure but trailed off into the unknown and found itself in the genre of crapness. DO NOT WATCH UNDER ANY CIRCUMSTANCES!!!
