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.
Accidental Innuendo: Eric takes Henry into his room to show him his hat collection. Everything was innocent, of course, but you have to wonder why Eric's mother didn't act a bit more alarmed when she found her son with a grown man in his room.
Fridge Brilliance: The entire world is so much more wholesome than ours, the thought that Henry might be a predator doesn't even cross the mind of Eric's mom. She's only upset because she wanted Eric to make friends his own age, rather than the adults he spends most of his time with.
On the contrary, she seemed quite upset at finding him there, almost disturbed.
Fridge Logic: Given this store is literally magic and actively displays this nature, how come this store is not an internationally known tourist attraction with a queue of kids and tourists several miles long every day?
It's arguably a metaphor for all of the little miracles that happen all around us that many people don't notice.
Fridge Brilliance: The entire movie, Mahoney plays the 'air piano' and music plays. The audience assumes it's just a directorial quirk, until the end, where Mahoney realizes she does possess magic. The magic was there the entire time, but we didn't notice.
On top of that, it's cleverly set up earlier. The term 'sparkle' is used as a metaphor for the magic inside Mahoney, and in the scene where she asks Mutant about it, the dialogue goes like, "You've got that thing you do with your hands." "That's a quirk." "Quirk's not a sparkle?" The film's screenplay just became even more brilliant.
Memetic Mutation: Films and TV shows love taking a shot at the film, either as something akin to whimsical torture (as in Breaking Bad) or scene dissonance (as in Brüno).
