These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Space Children
Moral Event Horizon: Ostensibly the blob crosses this line when it kills Joe. But then, no-one cares.
In Blobby's defense, Joe was beating his stepson rather severely, had threatened to break his neck and, in his drunken and enraged state, might actually have done so. Those who aren't openly attacking the blobs agents are dealt with non-lethally, and even when one of them tries to smash the blob with a rock, the blob merely destroys the rock.
Special Effects Failure: Whenever the blob emits a burst of light as part of its psychic attacks, it casts shadows of the actors and props on the "sky" behind them.
