Lost was a watershed moment in many ways, even though JJ Abrams couldn’t stick the landing. They rushed out the DVDs of season 1 about a month before the season 2 premiere, giving people time to binge the whole show (even the pirates). As long as the streaming services keep the back catalog around, you can always catch up. I have forgotten which show, but there was a network show I stopped watching because they only had the last six episodes on their app. Once I fell seven episodes behind, I didn’t want to keep going, having missed a chunk of the story arc.
There’s a certain level of curiosity for a show that has survived, say, six seasons. They must have something there if they keep going. Maybe I should check it out? Especially if I’m out of other stuff. But is it going to have a satisfying final episode, peter out, or end ina cliff hanger? The more seasons, the higher the likelihood for a wrap up. Two season shows almost always end abruptly.
