I know that George P. Cosmatos' Cobra ('86) has a shoddy reputation that has blossomed into an almost sarcastically cult-fashion today, but I'm not afraid to admit that I kind of love it.
It's rather obvious that Stallone had seen and loved Dirty Harry, Magnum Force and Bullitt and his script doesn't have an ounce of credibility (the ending doesn't make any sense), but this is just a cool 80's retro-actioner about a one-name cop tracking down a group of militant radicals.
Cosmatos' direction is a bit nebulous at times when the action picks up, but he fits in enough weird 80's music-video moments ("Angel of the City"), psychopathic villains (Brian Thompson) and one of the greatest car chases that I've seen.
Plus you have that Wendy Carlosesque synth score and the ultra-hot Brigette Nielsen before she starting appearing on low-rent reality shows and dating Flavor Flav. For my money, Cobra ('86) is a better good/bad movie than Commando ('85).
