The truth about MI --> 1. It was a phenom at the time. Clever plotting. Amazing characters. There was a formula to the show but it was new so viewers could not anticipate. Color TV was new then too and this show was believe it or not one of the reasons many reached for their wallets and made the plunge. 2. Steven Hill was fired because he was religious and made the crew work around his schedule. The producers were furious and went with a "famous" Hollywood name (family) to replace him, ensuring no more problems. 3. Bain and Laindau were married in real life. Hollywood had not seen that before in an espionage drama. 4. Lupus had virtually no speaking lines. Today no agent on the planet would let his client into that sort of deal. 5. For viewers of the present it will not hold up. Too much new technology has raised the bar. Even at that, it was a "budget" show in its day and many of the tropes simply will not stand the test of time.
