probably one of the best action films of it's time Really, one has to take into consideration the time frame under which this movie was produced. We were *still* (11 years later) feeling the sting from a "not quite a loss, but certainly not a win" in Vietnam, followed on in the early 80s by the failed hostage rescue in Tehran. Lastly, the early 1980s marked the rise in airline hijackings. This movie was more designed to renew the public's faith in our special forces and encourage a sense of patriotism (queue gratuitous scene of applying the American flag patch on everyone's shoulders). The soundtrack worked to the same end (at least half of the videos I saw filmed on base when I was younger used the soundtrack at some point).I can still recall seeing this in the theaters the week it came out, and no one left with anything but a smile on their face.
At the time it was released (1986) Delta Force was very much on par with any other effects-driven action movie of the time (the "Rambo" series, "Commando", etc) using props and technology that were still considered state of the art. (ok, it's obvious the pave-low that blows up at the beginning of the movie is anything but a Pavelow, but c'mon...) By modern standards, the movie is very dated. We've become a lot more attached to a consistent storyline supported by believable costumes and props (unguided rockets and mortars mounted on a motorcycle *were* a little "out there" for the time... and marine covers on an army uniform are a no-no) but again, it is no different than any of the other films of the time.
Basically, if you liked any of the 1980s action films, strong chances are you're going to like this one. The storyline is still (unfortunately) one we can very much relate to, which I suppose goes to show some things may never change...
