It doesn't take long to see why Code Name: Diamond Head didn't make it onto the network schedules. The TV pilot movie doesn't get past the credits before it's obvious just how bad it's going to be. Maybe I missed something, because the plot didn't make a whole lot of sense. Based on what I got out of the muddled mess, a terrorist or thief or something named "Tree" (Ian McShane) goes to Hawaii to steal something to do with a secret weapon. The world's dullest secret agent, Johnny Paul (Roy Thinnes), is out to stop him. There might have been more, but trust me  it really doesn't matter anyway.<br /><br />Action movies should have action. Suspenseful moments should have suspense. And dramatic moments should have drama. There's none of that in Code Name: Diamond Head. I've seen others use the word "turgid" to describe this made for TV snoozer  and it's better than any one word description I can come up with. None of the characters is in the least bit exciting or worth caring about. And Roy Thinnes makes for the worst leads imaginable. His charisma is just slightly north of a slug. Ian McShane is easily the best thing the movie has going for it, but unfortunately for everyone else involved, it doesn't appear he was going to be back as a regular cast member. Now if McShane had been cast in the series lead, well then you might have had something.<br /><br />I'm quickly discovering that these Gawd awful 70s made-for-TV movies make great Mystery Science Theater 3000 episodes. And that goes double if Quinn Martin was involved. Very funny stuff from Mike and the Bots. So while I may only give the movie a 3/10, I rate Episode #608 a 4/5 on my MST3K rating scale.
