800 votes at the time of writing and 4/10? C'mon, this film deserves better than this.If you haven't seen it,please do. There are no fancy effects, expensive sets and highly paid actors, but there is an entertaining story that will draw you in and have you routing for the 'good guys'.Why pulp films, that have ridiculous things like helicopters flying "impossibly" through tunnels, get such high scores whilst films like this are left going dusty on the shelf I will never know.It's not going to win any awards, but it is well worth a watch.6/10

This low-cost Canadian produced presentation is reasonably ordinary, but for its type not as terrible as it's made out to be. This is one of those films that the cover artwork always made it look quite interesting, but the synopsis on the back had less of an affect. A friend of mine convinced me to watch it, after the first half-hour I could see why because the story does such a great job setting up the highly-charged, innovative predicament (three astronauts in space watch on as world war three erupts with nuclear attacks on Earth) to only lose its way when a couple months later they crash-land back on earth then it becomes a very vanilla-like post-apocalyptic Sci-fi wasteland survival outing (of the very cheap, rancid b-grade kind) with some very unbelievably trite villains that come off more as joke than anything truly threatening. The head honcho played by Kevin King seemed more suited in a "Save by the Bell" episode, than as a ruthlessly imposing leader. At times I was waiting for cued laughter from an audience whenever he was on screen, as he came off more so a brat. Just as poor was Tim Choate in the leading role. Well more so eccentrically annoying. I found the support to be much better; Kate Lynch, Lenore Zann (running around in a school uniform), Maury Chaykin and John Walsch. The opening first half-hour is very well pulled off; with some striking visuals, solid set-designs and usefully gripping details. You could see where all the money went in to, but that could probably explain its weakly conceived abrupt ending. Maybe that had run out. Anyhow during its grounded action, it does create some nasty touches, edgy activity and cement an ugly intensity. Too bad it just too daft (simply lacking the colourful craziness) and at times incoherent. The story is straight-forward, although the script is flimsy and too black and white to make it completely fulfilling. Minimally junky and grim, if particularly plain post-nuke entertainment.

A group of American astronauts orbit the Earth in a top secret nuclear warhead carrying spaceship. Suddenly World War 3 breaks out down below and the ship is unexpectedly put into a program to land. On arrival on the planet, they are soon captured by a warlord who has emerged after the war.Def-Con 4 is a low budget Canadian attempt at a post-apocalyptic sci-fi action-thriller. These films were ten-a-penny back in the mid 80's. They were often low budget but full of enough action and violence to get away with it. This movie certainly fits the criteria but it fails to impress. I think this is due to a mix of things. The budget is perhaps TOO low, meaning that the sets are very limited. There are also no characters to get overly excited about. There's no one really worth rooting for and that doesn't help. And finally, the story line just seems so under-developed and almost random. It's taking the audiences credibility to the limit to think that the day after a nuclear war, the general population will resemble a Mad Max movie.Not terrible but not good. If you have a tolerance for cheesy and cheap 80's sci-fi movies then you could find something here of interest.

How bad can a science fiction movie get? Fred Ray Olen - the master of shitty sci-fi flicks - would die of envy if he ever saw "Def-Con 4". This is by far the worst movie I've ever seen. Lousy effects, crappy story and BAAAAAAAAAAAD acting. Sometimes movies are so bad you sit there with that B-movie smirk - smiling because the flick stinks so much that it actually (and unintentionally) is funny. Here - I just wanted to rip my my own head off and feed to it to the smelly Golden retreiver next door - hoping that the furry menace would choke on my tortured eyeballs.This is what the back of the DVD-cover says: Three astronauts return to Earth two months after a nuclear holocaust and find disease-crazed humans wandering through shanty towns constructed from the refuse of the previous civilization.And your next question probably is: What the f..k!!! DVD-cover? Did you actually rent or buy this crap? Nope, got it for x-mas 2004 as a part of a 5 disc/10 movies boxed-set named "SCI-FI - 10 GREAT FILMS!".Riiiiiiiight.....
