The Gremlins will get you if you don't watch out!" poster
The pattern
This still is filed under Us-versus-them positioning.
Define
The buyer is invited into a side. The product is what we use. The named other is what we refuse.
Mechanism
Identity contrast. Choosing the offer is choosing a group. The out-group does as much work as the claim.
Verdict
The category is crowded
Why it works
Externalizes human weaknesses (laziness, substance abuse, tardiness) into concrete, mischievous enemies (gremlins) that must be actively fought off. This cautions the audience without sounding overly preachy.
Steal this when
You want to caution an audience about bad habits without lecturing them, by personifying the bad habits as an external enemy.
