If I'm listening to a speaker, I'm there to learn. If I knew everything already, I wouldn't be wasting my time. So my intelligence is not insulted if the speaker assumes I don't know things.
It's possible to tell people new information with or without misjudging their capacity to follow, and with or without being boring. All those combinations happen out there.
Just like a book or a movie, your audience has to be able to notice that you're taking them somewhere, without being able to piece the whole picture together until the reveal. If you circle around a concept for a while, slowly inch towards it, and press the Next button on your remote like the grand unveiling of a marble statue, the reveal better be worth the buildup. The other extreme exists as well. Make it too cryptic, and people will have no idea what your point is.
No one appreciates having to wait through the slow exposition of something they already figured out. Spend too long revealing something you've already given away, and people will sleep through your snazzy powerpoint reveal transition FX.
You want presentations to be entertaining because people remember information they're interested in! It's not showmanship for the sole sake of the dazzle. Get people's attention, and your slides stick.

Itβs common for people to rewatch movies they have already seen, and reread books they have already read. Sometimes the joy is in the presentation, not the destination.
