I've always been satisfied with single episode stories (save for two-parters and such). . .
Don't worry, you are not alone. . .
Same here. If I wanted to watch serialized television, I would have been watching daytime soap operas for the last 50 years. Mini-series like Roots
are about all I have the patience to sit through. I equate movies to novels, and television episodes to short stories. A serialized 12 to 24 episode television show for 5 years would be the equivalent of reading all of Dickens' works.
ETA: About the only other time serialized stories worked for me were the old Saturday matinee chapterplays from Republic and other studios, and old Rocky & Bullwinkle cartoons.
