4 Severus please
4. "Severus, please." (Harry Potter and the Half-Blood Prince, 2009): Quibble if you want (It made it clear Snape was on our side! It wasn't clear enough that Snape was on our side!) - but Michael Gambon's soft-spoken, heartfelt final utterance, delivered to a stricken, hate-faced Severus Snape (Alan Rickman) at the end of Half-Blood Prince carried just as much power as it did in the book. For a bonus point, watch Alan Rickman's face once he's done the despicable deed of killing his only friend and mentor. These small moments are the counterpoints on which the series hangs its mythic stature, and this one was pulled off brilliantly.
