The Lieutenant

I remember watching this show when I was 13 years old and I really enjoyed it. Now I'm seeing it again on the local HDTV over-the-air station. I wondered how it would hold up for me over the years and I'm very surprised after watching the show again that it really was quite a good show. I had some limited military experience not too long after the show originally aired, so now I'm watching the show for authenticity of the military, and it seems to be pretty much spot-on. Seeing how this is a Gene Roddenberry was the creator and producer of the show, I wonder if Gary Lockwood was ever under consideration for the role of Captain Kirk in Star Trek. I think he would have been great and wouldn't have "hammed it up" as much as William Shatner. But then of course, "The Lieutenant" lasted only one season so who knows what may have happened?
