Shows and TV

For me, it really depends on how long each episode is. I would say the sweet spot is somewhere between 6-10 hours worth of content, regardless of individual episode length. Any less feels like there isn't enough time for character and/or plot development, and any more, and I start to forget all the plot details. As it is, with many shows having 1-2 year gaps between seasons, I often feel I need to repeat the previous season just to remember what all was going on.
