I'm glad there are people besides me that aren't crazy about the current serialized style of storytelling. For me, there are 2 main, intertwined problems with it.
1. The individual episodes don't have any genuine payoff at the end. They only serve to build up the larger narrative, which may or may not be worth my time.
2. Serialized shows don't have the same rewatchability for me. I can watch it once and then I'm done, as opposed to my endless rewatches of stuff like Doctor Who, Star Trek, and Buffy/Angel.
Don't get me wrong. I hate the magic reset button that often plagued stand-alone shows back in the day, particularly Star Trek: The Next Generation, Star Trek: Voyager, and the first couple seasons of Star Trek: Deep Space 9, & Enterprise. I like a little bit of ongoing development in the story. But there still needs to be a reward for watching through to the end of an episode.
Even at its most serialized in Season 4, Angel still managed to keep the individual episodes interesting. Even though every episode ended in a breathless cliffhanger, each episode was like a different movement in an ongoing symphony.
Compare that to Heroes (which I only managed through the first 2 seasons), where there seemed to be no rhyme or reason to when or where each episode ended beyond "We filled up this hour, now wait for the next one."
Granted, sometimes the serialized stuff works OK if it's a short, self-contained story. Agent Carter managed to create 2 fairly tense, engaging 8-part story arcs. But when it's really open-ended multi-season stuff like Game of Thrones, Orphan Black, Stargate Universe, or The Walking Dead, I just can't manage to get too engaged, regardless of how interesting I find the characters. (I did OK with Battlestar Galactica but eventually gave up because I realized that I hated almost all of the characters. I still own Season 4.5 but never took it out of the cellophane.)
Generally, what I prefer is shows where the episodes are stand-alone but there's still an over-arching development for the characters, like the majority of Buffy & Angel.
Meanwhile, maybe it's just aging, but there aren't any current SF/F shows that I'm following any more except for Doctor Who & Red Dwarf. I lost track of Orphan Black after Season 2. I tried Supernatural but couldn't muster much interest in either Sam or Dean. (It's a bad sign that I always have to pause and remember which one is Sam and which one is Dean.) Several shows are on my eventual "to watch" list like Agents of SHIELD, Arrow, Daredevil, Dark Matter, The Flash, Grimm, Killjoys, Legends of Tomorrow, Once Upon a Time, Sleepy Hollow, Star Wars: Rebels, and Supergirl. Maybe I'll try a complete binge-watch of Game of Thrones after it's over if I can find a cheap complete series box set at Costco. But, honestly, the length of that list discourages me from even starting it. It's easier to just curl up with my old DVDs of Law & Order and classic Doctor Who.
