RyothChatty ridiculous rating

Humaira Grant It’s not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.

Mabel Munoz Just intense enough to provide a much-needed diversion, just lightweight enough to make you forget about it soon after it’s over. It’s not exactly “good,” per se, but it does what it sets out to do in terms of putting us on edge, which makes it … successful?

Matylda Swan It is a whirlwind of delight --- attractive actors, stunning couture, spectacular sets and outrageous parties.

merklekranz What starts off as a reasonably interesting sci-fi, suddenly morphs into "Mad Max" nonsense on a zero budget. It's as if all the money was spent on the space stuff, and then the rest was filmed in a junk yard to finish things off. The strong writing of the beginning gives way to dark shootouts. and stupid dialog. Rarely does a film so suddenly descend into oblivion like "Def-Con 4". I really liked everything right up until the astronauts began digging their way out of the half buried space capsule. Once outside, other than the welcome appearance of Maury Chaykin, everything is totally unacceptable from an entertainment perspective. My conclusion is that for a low budget sci-fi, there are far worse out there, but the missed opportunity here is regrettable. - MERK

Red-Barracuda 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.

doug1717 I bought this film at a used movie sale. I remembered the title and the poster from way back, and for some reason I had it mixed up with another apocalyptic flick called "Twilight's Last Gleaming". Also I saw the name Tim Choate. I recalled he was "Zathrus" on the show "Babylon 5". I should have saved my money. Very poor production values, although the orbital weapons platform parts looked pretty good for a bad film, the rest of the film is hazy and crappy, and poorly lit. There is no real dialog, it is just bad. The film was made with Canadian Government tax dollars and they put in several things to show the flag, like the weirdo in the kilt who made booby traps with Canadian Government issued Social Insurance cards. Go figure! The characters are terrible, the acting is laughably bad, this film just stinks. You can't even say that it is so bad it's good, it is a lazy effort that makes no sense at all. And Tim Choate's best work was on "Babylon 5" under all that make up.

leathermusic Def Con 4 is one of those movies that is pretty much unique in the world of B grade cinema. First off, why do so many imdbers dislike this? There are thousands, perhaps millions of movies far worse off. The acting and special fx are actually pretty good for such a low budget film. The beginning of the film has a great sense of dread. The music by Christopher Young is awesome! There is some over top emoting from the lead actors that is slightly lame, but overall a good relic from the cold war. This may be one of the more underrated Canadian sci fi movies of the 80s, although much of the plot and characterizations goes way lame in the second half. In summary, it's a good bad movie that is more good than bad.
