I agree 100% that serialised stuff is harder to rewatch since it's an investment of 10-15 hours (or a lot more in DS9's case) rather than 45 minutes and life doesn't always allow that. But I still enjoy modern TV for what it is.
I'm of the opposite view. I can watch serialized shows more easily because I can go from one to the next. I want to see what will happen next.
Well, I wouldn't just talk about the difference between serialised stuff and procedural stuff, but I would say, that it's harder for serialised stuff to earn
rewatchebility (when it comes to the first time of watching, I also would agree Lord Gareth), because it all depends on the way the story goes and the finale:
- When a procedural has an ending, I'm not totally happy with, it doesn't have an effect an all the stand-alones between the few arc-episodes. Than I can easily 'forget' about it and enjoy the rest. I didn't like the storylines in 'Eureka', but I can still watch the episodes, because I like all the crazy technique ideas in the standalones.
- When a serial has an ending, I didn't like much, it has a great effect to all the episodes before, that lead to this ending. I just don't see the point in it. I enjoyed a lot of episodes of LOST or GoT (and they both will always have some of the best scenes/episodes ever), but since the end were such a great disapointment, I never had the motivation of a rewatch.
For me, both arcs - PIC season 1 and DSC season 2 - had a very disapointing resolution.
