Years ago I *started* to watch a 1978 TV series called "Dallas" (or a 1981 TV series called "Falcon Crest"? hmm) but I abandoned it (or it) when I realized it (or it) would just go on and on and on without end.
Years ago I started to read and *continue* to read 1994 Speculative Fiction series called "Foreigner Universe" that *amazingly* continues to this day.
Why? Because "Foreigner" begins each episode/novel/arc with a situation and ends each novel with a happy resolution.
Dallas ran 13 years/394 episodes. Foreigner is running 22 years/17 novels and counting.
I am sure they are both good however I admit I am biased for Foreigner *sigh* please choose your own preference!
