After "Rocky" and its sequels, Sylvester Stallone cast about for another character that would bring him the same kind of box-office hit--and found it in disillusioned Vietnam vet John Rambo in "First Blood", a solid little action thriller. So when all else failed, Stallone went back to the same well in hopes of recapturing the same commercial success. Which this film did. But where "First Blood" was a no-nonsense thriller that pitted Stallone against a worthy (and not necessarily bad) Brian Dennehy, this one is a sadistic chest-thumper in which Rambo gets to go back to Vietnam: ostensibly, he's there to rescue missing POWs, but in fact the movie was a lame excuse for him to refight the Vietnam War--and win. Audiences ate up the cruel Vietcong (and their Russian manipulators) and Stallone's bogus heroics, but it was strictly by-the-numbers action. "--Marshall Fine"
