Worth the time?
Committing myself to a series, especially if the show goes on for multiple sessions is a big decision. I watch tv so little that I wouldn't want to waste my time on just about any show.
It's hard yo judge beforehand. Good story or book adaption doesn't guarantee a good show. Original story can be as good as a literary classic and even those classics can be ruined by so many things. Not least by the high expectations they tend to raise.
With books I can always switch to fast reading if I find the story uninteresting or slow. It's harder to speed up videos.
