Since I did not expect an action-packed on-your-the-edge-of-your seat film, I was not disappointed with this movie.
I saw it as basically a character study, between an older, more experienced man (Tom Berenger), and a younger, inexperienced and proud man (Billy Zane). They are foisted together on a jungle mission, and while Zane's character is *supposed* to be the superior officer, he soon learns that he is out of his element. Berenger's character calls him "son" as he leads him through the jungle, being simultaniously irritated yet supportive over Zane's inexperience.
I found myself caring about these characters, and appreciating the contrast between them. While this film had flaws (the ending, while adequate, lacked a little "punch"), I still enjoyed the movie overall. The performances of both actors was good -- particularly Berenger, who does the "steely emotionless" thing quite well. Zane was also good at looking a little queazy and out of his element.
I found this movie to be a worthwhile viewing experience. I hear that "Sniper 2" has been filmed (Berenger reprising his role), so I am interested in seeing what Berenger's character is up to now.
