Film/TronLegacy is even ''more'' [[DarkerAndEdgier dark and edgy]] than [[Film/{{Tron}} the first movie]], so expect some scary moments.
----
* This moment fairly early on, when Sam initially thinks Clu is Kevin Flynn. Even though he figures it out before Clu confirms it, it's still unsettling.
-->'''Clu: [cheerful smile]''' I'm not your father, Sam.
* Clu's speech about his plot, [[spoiler:which inverts Flynn's hopeful speech to Encom]].
* Most of the henchmen are Repurposed Programs. They are not doing this of their own free will. What makes it worse is that Sam may be killing innocent programs and not know about it.
* Some of the programs' deresolutions are rather... [[{{Gorn}} unsettling]], to say the least.
* Somewhat funny, mostly freaky:
-->'''Sam''': What's his problem?\\
'''Program''': (missing half his face) '''''*growls*'''''
** Soon after: '''''"ERASE MEEEEE!"''''' *[[BetterToDieThanBeKilled jumps to his death]]*
*** He doesn't just fall, ''he gets sliced by the rotor blades!'' We don't get to see any gore since he's a Program, but ''he shatters,'' which makes it even worse.
* [[IHaveYouNowMyPretty The way Clu acts towards Quorra]] when he captures her is [[http://www.youtube.com/watch?v=3T574MgpKFo&feature=related creepy]] Seeing him [[{{Squick}} touch Quorra's hair]] and announce that he has [[GettingCrapPastTheRadar "something special'' for her at his quarters]] drives the horrific scene home, especially when you realize that Quorra, [[spoiler:[[LastOfHisKind the last ISO]], is trapped by the program who [[FinalSolution utterly annihilated her race.]]]]
** The UncannyValley effect for Clu doesn't help matters either.
* The film also has a few terabytes of FridgeHorror. Flynn Sr. has been [[AndIMustScream trapped on his Grid for the equivalent of 1000 years]], watching all his friends die, his dreams decay, the [=ISOs=] be slaughtered, his creation run amok with no way to stop him, and no way to die or escape! And then there's the thought of what must have been done to create Rinzler...[[spoiler: Clu managed what Master Control couldn't. He ''broke'' the biggest LawfulGood {{Badass}} on the Grid into a near-feral killing machine.]]
* Speaking of Rinzler, that 'purring' that he does. It can sound too much like [[Film/JurassicPark Velociraptor]].
** And speaking of Rinzler's purring, FridgeHorror ensues when you imagine what Clu must have done to him to make him sound like that. It's coupled with the fact that, until the end of the movie, Clu's got him completely under his command, and that it might have something to do [[spoiler:with the massive scars Tron has on his neck that we've seen in uprising.]]
