yes, a very important line to tread. as a creator, it is so hard to axe something you’ve worked hard on, but drama thrives on this. the horror creature’s presence is implied, but not seen; it is shown in only in shadow until it strikes and then is gone. the vaudevillian maxim “always leave 'em wanting more” or the stand-up comic version “always end on a big laugh.” to do otherwise is, as you say, begging your audience for attention. Also, as you say, it takes maturity to begin to notice and feel insulted by it.
cheers.
