There's nothing even remotely askew in anything Jeri said. There are
two philosophies at work here (arc vs. non-arc), and neither is
intrinsically or inherently better than the other. It's a matter of
personal tastes, and what you're trying to accomplish.
The Martian Chronicles was written as a series of short stories within
a universe, somewhat loosely, but which together make enjoyable reading in
one volulme. That's ST or most conventional series.
The Dune books are tightly plotted stories over a long, pre-planned
arc. This is the structure B5 employs.
