The multi-year gap kills my interest. After a huge hiatus, I have forgotten key plot points, so I have to either accept that some elements will not make sense or commit to re-consuming the original season. Both of which are deeply unappealing.

I keep meaning to watch Arcane season two, but the first one was so dense (not necessarily plot, but just so many little things) that I know I would be cheating myself to watch it after the sizeable gap. Yet rewatching S1 just to start S2 is such a time commitment.
