A simple scene will only have a very slight effect on the reader.
A sequence of more complex scenes (especially a series of scenes that build) will have a moderate effect on the reader.
A turning point, or a climax, should have a major effect on the reader.
(With a turning point, of course, the change is irreversible.)
(More insights from Robert McKee!)
Knowing this, think critically about every scene in your novel. Which scenes get the bulk of the attention and/or take up the most emotional/dramatic space within your story?
If the scene is meant to be simple, keep it simple (and don't expect it to do something it isn't meant to do or try to turn it into something it isn't).
Of course, it's also worth it, then, to determine how this simple scene affects the plot as a whole. If you were to delete the scene would its disappearance affect the story in a negative way? If the answer to this question is no, then odds are nothing of value is happening. In this case, consider removing it permanently or revising so that it carries more weight.
Even simple scenes should move the plot along, but keep them simple. That is, know which scenes should affect the reader most and give those the attention they deserve.
Be Brilliant!
