I would submit that the storytelling and lyrics/dialogue are not always gonna be of the same quality.
For example,
The Matrix is a great story, but the dialogue ranges from mediocre to average.
Comparatively, "The Best of Times" is a great thing to write about, the life of one's father who is dying, but the actual lyrics are not what I would call great.
Conversely, many would say that the subject matter of some of Rush's early material was somewhat cheesy, the fantasy stuff, but Peart's actual lyrics were almost always brilliantly written, even if it was about something that wasn't a great story, per se.
Does that make sense?
