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.
Covers Always Lie: The DVD cover features the three main characters on a winged horse above a medieval-looking castle, neither of which remotely resembles anything that appears in the film. They Just Didn't Care.
First Installment Wins: Ever heard of A Wind in the Door, A Swiftly Tilting Planet, or Many Waters? None of them got Newbery medals.
A Swiftly Tilting Planet did win the American Book Award in 1980.
Fridge Logic: Wrinkle comes under scrutiny when the characters of When You Reach Me discuss it. Specifically, Miranda and Marcus discuss L'engle's portrayal of time travel. The three Mrs. W's promise Meg and the boys that they should be back "five minutes before you left." But as Marcus points out, if this is true then Meg should have seen herself returning, because Meg&co. landed in the garden, which in plain sight from wall, where they left. Marcus is arguing a Stable Time Loop is in effect, while Miranda (very defensive of her favorite author) maintains that the future hadn't happened yet, so of course they wouldn't be seen.
Fridge Brilliance: There is a simpler explanation, which no one in When You Reach Me notices: Mrs. Whatsit says they'll be back five minutes before they left, unless "something goes terribly wrong." And something does indeed go terribly wrong.
L'Engle: Oh, yes. I expected it to be bad, and it is.
To be fair, Kyle Secor does make a good Man With the Red Eyes.
Viewers Are Geniuses: Scientists' reaction at the time of this book's first printing. They couldn't understand how something as advanced and theoretical as quantum physics and tesseracts could be accessible to children.
