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.
Fridge Brilliance: Scary German Guy mentions how he knows about real monsters. Then as he closes the door, you can see a concentration camp tattoo on his forearm, which many kids would not recognize, but parents would.
Frankenstein's monster once again befriends a little girl... but this time, he saves her from being killed.
Fridge Logic: Many questions regarding Dracula and his monster gang. What was Frankenstein's monster even doing on the plane? If that man was a werewolf to begin with, how come no one noticed up until now? Where did the Gill-man come from? Where did Dracula get his car? How can he even summon these monsters to begin with?
How come only female virgins count? That could have saved the kids a lot of trouble.
The Gillman was apparently in the second crate aboard the plane.
