I was wondering which single scene out of the Harry Potter series you 
think is the best?  In other words, if you were trying to convince 
someone (who has read the books) that the series is really something 
special, which one scene would you direct them to?

The scene I found most intense and most moving is the Shrieking Shack 
scene in PoA, beginning from the point at which Harry enters the 
Shrieking Shack to the point when they emerge from the Whomping 
Willow.  The pacing is really fast, the story unwinds and is 
explained in a very believable way, the very best characters in the 
series (IMHO) are present (H, H, R, Lupin, Sirius, Snape), the 
Scabbers plot twist is brilliant, and the relationship that develops 
between Sirius and Harry in this one scene is very moving.  Indeed, 
each character is developed substantially in this one scene.  JKR 
couldn't have done anything to make this scene work better.
