def con 4 be one of those movie that be pretty much unique in the world of b grade cinema . first off and why do so many imdbers dislike this . there be thousand and perhaps million of movie far bad off . the acting and special fx be actually pretty good for such a low budget film . the beginning of the film have a great sense of dread . the music by christopher young be awesome . there be some over top emoting from the lead actor that be slightly lame and but overall a good relic from the cold war . this may be one of the more underrated canadian sci fi movie of the 80 and although much of the plot and characterization go way lame in the second half . in summary and it a good bad movie that be more good than bad .
