Completely true. (Why do I always end up quoting you?!

) I love twist endings where I go, "My goodness! That makes so much sense! I should have caught that!
Argh!"
However, in my experience as a reader, there's one other thing I can find a bit annoying in a twist ending: a long explanation right after The Reveal. I think this can work if the reveal is during a slower part, or if your book just has a slower pace...but if you get the twist right at a dramatic point, I may not appreciate a long explanation following, particularly if I already mostly understand what happened! The twist in Jennifer Nielsen's
The False Prince wasn't the best in this regard, I think. Directly following the reveal, she spent about a chapter (if I remember right...it's been a while) describing all these scenes that had to do with it, kind of going on and on...
But then there was a twist in Rebecca Stead's
Liar and Spy (which, overall, I thought was great, by the way) which was also accompanied by quite a bit of explanation...but
Liar and Spy already had a pretty slow, thoughtful pace, and I felt like it was better and more elegantly done than the one in
The False Prince anyways. In particular, Stead had to explain the thinking behind a character's actions, and she did this by having him tell a story...which I thought was very nicely done.
In a fast-paced book with a twist at the ending, I generally prefer the author to suddenly reveal what's going on...leaving you saying, "Wait!
What?!", reading furiously, a bit confused, trying to piece things together...until finally everything's unsnarled and explained in the denouement, once the climax is done. I think Brandon Sanderson may be the master of this type of ending. I've read six of his books and four of them had very good twist endings. (One of the others had an attempt at a twist that fell kind of flat. I didn't see enough clear foreshadowing, so to me it came out of nowhere...but other readers did see lots of foreshadowing,
too much foreshadowing, and so it was too obvious.) All of them involved a sudden realization in the middle of a tense scene, some quick thinking to take advantage of the reveal, and then, finally, after the climax, a full explanation. Or, actually, in two of those cases, the main character still doesn't understand what's going on even after the climax, and so the explanation is presumably left for the next book...annoying but in a good way.

(Except for the fact that in one of those two of those four cases, the next book may never be written. But anyways!

)
TL;DR: Please, if you have a big twist at a dramatic moment, don't take a long time to explain what's going on. In my experience, if the writing is good, I don't care at the moment about understanding exactly what happened. I'll let myself be swept through the scene and will happily accept explanations later.
