Mrs. Desjardin, or Ms. Collins slapping the shit out of Chris was pretty awesome, considering how much of a bitch she is.
Even better, in the 1976 film, Chris tries to get people to side with her, but they don't even care, as proved when Sue tells her to shut up. It shows that Chris herself wasn't as popular as she thought she was.
Special mention to the school officials in the 2002 remake (and the original novel) who not only ensure Chris is punished for her actions, but also deliver a legal slap to her father's face when he actually attempts to sue them for suspending his daughter by threatening to file a countersuit on behalf of Carrie. The school official also makes special mention of Chris's numerous cases of harassing students.
Special mention goes to the Principal. Sure, he doesn't say Carrie's name right, but he stands up for her anyway.
There's also the 2013 version, where Miss Desjardin shuts the lawsuit threat right down by showing her father the YouTube video that Chris put up of the prank.
In the 1976 film, Carrie showing her powers to her abusive bitch mother for the first time. "Things are gonna change around here..."
Carrie:(in the midst of an argument with Margaret) Momma, come back here!
Margaret: The rain's coming in... I have to close the windows.
Carrie: I'LL GET THEM! (she slams the windows shut, one by one, with her mind, scaring the crap out of her mother)
And while Margaret of course goes into a God-fearing panic, Carrie calmly sits back down and finishes her dinner. End of act one.
In the 2013 film when Tommy calls the English teacher an asshole for being rude to Carrie.
The 1976 prom scene on the whole, despite being Nightmare Fuel for most, is pretty great to watch on a cinematic/artistic level.
Thirty seven years of technological advancements later, 2013 film amps up the destruction to truly sublime levels, the least of which is the Perfect-Cell style shockwave which sent the stadium of bullies flying that opened Carrie's rampage.
Special mention includes Carrie causing Tina's dress to catch fire, not long after she posted the locker room video for the whole class to see.
The little showdown between Carrie against Chris and Billy in the 2013 remake, as Carrie literally tears the road apart to stop their escape and tossed them around like so-much toys while they were in their car. Chris tries to get a villianous one when Billy is killed, by pulling a Determinator by trying to kill Carrie again, but the crowning moment goes back to Carrie when she smashes Chris's face through the windshield before throwing her into gas station tanks.
The final act of the 2013 version can easily be called CarrieMeetsDragon Ball Z; and that's quite a fine compliment for a remake.
"The Destruction" from The Musical, which is a song just after the blood gets dumped on Carrie. On the revival's soundtrack, Carrie's actress's singing had been good, but nothing spectacular. Then, in this song, she belts out: "Doesn't anybody think that I hear?!", and just like that, you know why they cast this girl.
