This show was one of the Super heroe classics of the 70's. For its time, the effects were pretty well done for 70's television. One needs to remember that this was before computer aided effects and even fiber optics. They were done the old-fashioned way: smoke, mirrors, and magic!
Lee m ajors did a good job with the part for the first few seasons. of course, I am sure the role got old and it became harder to see Majors as an Air Force Reserve officer with the haircut he sported. Still he filled out a set of dress blues very well.
Richard Anderson played oscar Goldman very well. His cool dimeanor worked well for the part of a cold, calculating, Washington-type.
Maryin E. brooks was the best Dr. Rudy Wells of the series. I wish he had showed up before the third season.
