My oldest son and I just finished watching the first season of the original Star Trek series. We watched the episodes in “production order,” meaning the order in which they were filmed. That way, we could see the growth of the show, the way the actors find their characters, and how the Enterprise itself is more and more developed. Here, then, are some observations.

1) William Shatner hits the ground running as Kirk.

It takes most actors a while to find their characters. Leonard Nimoy doesn’t really nail Spock until several episodes in, which is understandable since no one had ever quite done a character like that before. But Shatner is the Kirk we know and love from his first episode, “Where No Man Has Gone Before.”

The most surprising thing I noticed this time through the first season is how often Kirk loses his temper in a crisis. It’s never an explosion of violent anger, but he snaps at his people a lot. To his credit, he also (usually) immediately apologizes, but for the first time I got the sense that serving with Kirk might not be that much fun.

2)  The Enterprise was not always terribly thought out.

In “The Enemy Within,” Mr. Sulu and his team are stuck on a planet’s surface by a transporter malfunction, in danger of freezing to death. Subsequent episodes reveal that the Enterprise has a fleet of shuttlecraft (they first show up in “The Galileo Seven”), yet apparently at this point no one had thought of them, because simply flying down and picking them up is never mentioned as an option.

3) Hi-def does the show no real favors.

We watched the episodes on blu-ray, which includes the option for new CGI effects shots. I’m ambivalent about them; they don’t bother me, and they let “modern” viewers (like my son) get into the show without the jarringly grainy, old-school effects. But the non-effects shots are not tweaked. Wrinkles on the paper bridge screen inserts jump out at you, there are obvious stray threads on the costumes, and you can occasionally see Kirk’s command chair shake when someone walks nearby on the bridge.

This is supposed to be Kirk and Khan. How bad was TV reception back then?

But by far the most egregious thing are the stuntmen. In many fight scenes, Shatner and company are replaced in long shots by professionals; in the 1960s, when TVs were smaller and broadcast signals were analog, this probably wasn’t too noticeable.  But on big-screen TVs, in 1080p, there’s simply no missing it.

And finally,

4) The crew of the Enterprise are adults.

This may seem obvious, but I’m not talking about biological age. There’s an inherent maturity to the characters, in their responses and dilemmas, that marks them as grown-ups. Each of them has chosen their career in Starfleet because they believe in what they do, and want to do it to the best of their abilities. There are few slackers in Roddenberry’s Trek, no corruption in high places, and even when characters disagree and lose their tempers, they do so as adults. Even Kirk’s notorious way with the ladies isn’t depicted as anything immature; he simply likes women and is willing to spend time with them, but only when his job allows. In the whole first season, he has only one real romance; the cliche womanizing Kirk doesn’t show up until much later in the series. Contrast this with the immature, entitled “bro” Kirk of JJ Abrams’ films, who may chronologically be an adult but displays the emotional life of a seventeen-year-old.

I’m glad my son wants to watch Star Trek; I’m looking forward to starting season 2 with him. It’ll be interesting to see if his opinions match mine (his favorites from season 1 are “Shore Leave” and “The Devil in the Dark,” both respectable choices).
