I recently finished the first season of the old Perry Mason show from the 50's and 60s. I haven't watched it before - instead, I came to it after having watched the new, short-lived HBO show with the same title and almost the same characters. That gave me the reverse perspective from people who have watched these chronologically.
The HBO show benefits and suffers from a pattern of prestige remakes of old shows. In the old show you see defense lawyer Mason, his secretary Della Street, and his trusty private investigator Paul Drake, save a client from a murder charge by extreme means as of the first episode. In the new show, the first episode introduces us to Mason as a private investigator, Paul Drake as a police officer being, and Della Street as legal secretary to a lawyer who is Mason's mentor. The season ends with Mason transforming into a defense attorney, Street becoming his secretary, and Drake somewhat more associated with him. Mason's court nemesis from the old show, Hamilton Berger, is much more ambiguous here, and is a mere assistant DA. Lt. Arthur Tragg, the homicide detective and the one usually more closely involved in making a case against Mason's client, is not significant here. Since the show was canceled before it could be completely finished, I don't know how far they would go in reproducing the dynamics of the original show. Since it's supposed to be more closely based on the books than the original, it may never have been planned to reach that status quo at all.
The original show in light of all this is fascinating. It's a truly episodic show. There is no reference to earlier episodes, no characters develop in writing. Each episode stands on its own. They also all have a very similar pattern: we are presented with a non-deadly conflict, having to do with finances, emotion, or both - maybe someone is being blackmailed, maybe someone's heart is broken, maybe someone is being cheated out of an inheritance - and someone involved contacts Mason, and becomes his client. Then someone that was in conflict with the client dies, and Mason is diverted from corporate and real estate law to criminal defense. Mason himself often finds the body, and his law-stretching attempts to balance his duties as an officer of the court and his duties to his client bring upon him the ire of Lt. Tragg, who is not far behind. As more evidence is uncovered, Mason's client looks more and more guilty, until he comes up with an insight that lets him not only avert his client's conviction, but help Tragg and the district attorney, Berger, find the real culprit. Usually this involves the guilty party blurting out a confession in open court.
I watched a full season of this. In fact, many people, from the early history of television, and to this very day, watch shows like this, for many, many seasons. Shows in which the episodes are connected by the characters and the circumstances, but don't explicitly build one episode on the other.
It used to be suggested by the medium: in the time before VCRs, and with reruns and syndication depending on popularity to begin with, you simply couldn't depend on your viewers to have watched several shows in a row in order to follow any kind of serial narrative. You had to make every episode stand on its own, but you also had to make it reproduce the brand you were marketing. So repeating the same episode premise with some variation was a pretty reasonable design decision. Once you knew you had an audience, you could start playing with the medium more. You could end episodes or seasons with cliffhangers, and use those to encourage people to watch next time. You could change the status quo. That being said, you didn't have to.
So I watched 40 episodes (39 from the first season and one from the second). What did I get out of this? The writers did not present me with character growth. If you mixed the episodes up I wouldn't have been able to see the difference. But I changed. My frame of mind about the show changed. As I watched episode after episode, I got to see more and more of these static characters. Instead of seeing how Mason grew into his position, how he formed the relationships he has with his allies and antagonists, I saw Mason in this position, I saw these relationships, under many variations of the same challenges. I saw Mason and Tragg maintaining an almost erotic tension, so delighted to one-up each other, but with a certain moral commonality that meant that when Mason really managed to find out who the real culprit was, Tragg would cooperate with him, waiting in the wings to make an arrest once he'd pressured the guilty party, if he couldn't do it in court. I saw the legal procedures, and possibly understood them better - when it does make sense to object, when it doesn't. I could start seeing patterns of when it's clear that Mason or Burger were going out of bounds intentionally, as a rhetorical point, and when they've clearly been stymied by the other party, or by the behavior of a witness. If an episode did go in a very unusual direction - so far only one got all the way to a jury reading a verdict for one of Mason's clients - it could be used to examine the others in sharper relief.
I think that the process of a viewer of such an episodic TV show is like that of a player of a roguelike video game. A roguelike usually has the same general premise from playthrough to playthrough. However, the details are procedurally generated. In the more strict versions, you don't get to keep anything, so you can't build up a mechanical narrative of change as you play. What you do is learn, from session to session, about the laws of the world, of the patterns of action of the enemies, of the power-ups, of the dynamics of difficulty as you move farther and farther in, or travel farther and farther out. You understand existing things - those which don't change from playthrough to playthrough - better, due to how they interact, or how they relate to each other, through what does change each time.
Arcade games are similar. You play Galaga over and over. The game starts over each time, regardless of how well or how poorly you did in your last run. However, these games usually have a certain progression that is repeatable, so that you end up learning that, more perhaps than anything more inherent about your avatar in the game, or the enemies, or your power-ups. Often you can memorize some of the specific patterns enemies take in specific levels - in fact, depending on difficulty, it might be a requirement to advance.
So I think that (strict) roguelikes might be the best gaming exemplars of what I'm talking about. Might be time for me to try looking at this genre anew.
