Still working my way through TNG and I'm about halfway through Season 3.
I have to say, all this Star Trek binging I've been doing has really made me pine for more standalone episodes again.
Too many shows are worried about the season long story arcs (Marvel Netflix shows, I'm looking at you), but I'm finding myself really enjoying the episodes that tell a complete story. A beginning, a middle, and a satisfying ending.
I guess I've always been that way. When I watched X Files back in the day, I always liked the "Monster of the Week" episodes way more than the ones that dealt with the alien conspiracy, which got so increasingly convoluted, that I just stopped caring.
