In my experience having to sit through 8 crap discrete episodes in order to maybe find 8 that are worth watching is a very unpleasant experience. And I've abandoned every Star Trek series after TOS at some point because of too many crap episodes in a row because a 45 minute story Star Trek ep almost always lives and dies on the one point it's trying to make, and if it fails that single point that's it.
I dunno, since it's been so long since I've seen any Trek on broadcast. Over the last decade plus, the way I've watched Trek has been on streaming services, skipping the awful episodes and focusing on the good ones only. Really Discovery is the only Trek right now that I have experience with tuning in each week and thinking "hope it's good this time around...oh well better luck next time."
I mean, there's only a handful of Voyager episodes I consider good (instead of merely passable) but I can just go on basically any streaming service and just watch those episodes and ignore the rest, which works well for me.
But an 800 minute story has multiple points that carry on from episode to episode and across an entire season because no one episode is built from one single point. So, everything balances out because its almost impossible that any single episode will fail in its presentation of most of the threads going on. There aren't really any filler eps who blow their single point, even if there might be fewer eps that manage to nail every single point the series or season is trying to make.
That can also be a liability though. I mean, I love Deep Space Nine - it's my favorite Trek by far - but I know that if I am going to start rewatching it - unlike other Treks - I will feel the need to start from the beginning and work my way through, which means a commitment of months if not the better part of the year (I probably only have about two free hours a day on average, and I don't always want to spend them watching things). When you add to this a serialized show with which I have major reservations about sections of - like say Game of Thrones due to its last few seasons - taking on a rewatch becomes even more of a chore, often feeling more like taking medicine than something related to enjoyment.
Honestly, Disco is the first time ever I've watched every ep of the first 2 seasons of a Star Trek series in order and haven't felt I've wasted my time doing so.
Keep in mind though the first two seasons of Discovery have the same runtime as the first season of any other Trek show. Less runtime than a TOS season actually.
IMO, an 800 minute story isn't going to get it as a whole 'right' or get it as a whole 'wrong'. and that's its strength. Can't say the same for 45 minute stories though. In my opinion they have far more riding on getting it 'right'. And in my experience, Star Trek has struggled to do that with any consistency ever.
I'm not a big TV watcher, as I've said in the past. I'm much more of a reader, and I've gone through big periods of time where I haven't watched any TV at all. I stopped owning a TV around the year 2000, and until Netflix started doing streaming, I didn't really watch much TV at all unless I happened to be in a hotel or something.
That said, I've watched a fair number of serialized shows which have held my interest in recent years through the entire season with little complaint, like Stranger Things, Lost in Space, Altered Carbon, Good Omens, Carnival Row, etc. I've also tried to watch other serialized shows where I frankly lost interest halfway through the arc and stopped watching entirely. Discovery is in that middle section - like the last few seasons of Game of Thrones - where it holds my interest enough to finish the season (in part because of my commitment to the material), but it also seems replete with narrative errors which make it impossible to totally suspend disbelief.
