TRON: Legacy/Heartwarming

• This music video sums up all of the heartwarming moments so well, you will cry... and feel happy at the same time.
• Kevin Flynn telling his son "I'd give all of this up...for one more day with you."
• Sam and Kevin's reunion:

Kevin: "Sam..."
Sam: "Long time."
Kevin: "You have no idea."
*Kevin walks towards Sam*
Kevin: You're here....
*Kevin hugs Sam*
Kevin: You're... you're here....
Sam (tearful): I'm here...

• Quorra's childlike innocence.

Quorra: "Do you know Jules Verne?"
Sam: "Sure."
Quorra: "...What is he like?!"

• Sam telling Quorra about sunrises in the real world while making references to Quorra's beauty. This moment was beautifully heartwarming, especially since Quorra was always curious about the real world. More subtly, this helped ease her pain of being the last ISO. It also cemented Sam's and Quorra's growing love for each other.
• Sam showing Quorra the real world after escaping the digital world, starting with a Cue the Sun moment.
  • What's particularly nice about this is that it's not played like a typical romance sub-plot at all. They're clearly enamored with each other, but the attraction is expressed subtly with emotion instead of physicality. The romance is actually separate from the Fan Service.
  • It's also a Fridge Brilliance contrast to the ending of the first movie. While the first movie ended with a shot of a lit-up, nighttime cityscape, depicting that we are Not So Different from the computer world, the shot of Sam and Quorra taking the bike and seeing a sunrise far from the city and electronics showed that we are different, after all.
  • It's also worth noting that after seeing the sunrise, Quorra rests her head against Sam's back while staring at him throughout the whole ride. Whether it goes anywhere is up to the viewer, but the look she gives him implies she finds him just as attractive to the eyes as he does to her.
• Sam reminding Kevin about how they promised that they would play on the same team.
  • Which led to a hilarious reaction from Kevin.
• In its own way, Kevin hugging Clu as he derezzes and reintegrates into his body. Sam is one son of Kevin, while Clu is the other, so the parallels are striking, especially in light of Kevin's apology and unspoken forgiveness toward Clu and the mistakes that he, Kevin, had made in creating him. It's a powerful moment that, like the truly greatest ones, is told through simple gesture and body language.
• "I fight for the Users!"
• Kevin's reasoning for saving Sam. "He's my son."
  • Not just that. Kevin is giving up everything he'd worked for in his time imprisoned on the grid, even his Zen, man. Everything.
• When Sam tells Quorra, "Made it," when they get to the bridge after she said they wouldn't make it (a Call Back to the conversation they had when they first met, with the lines reversed), the normally stoic Quorra grins widely for the first time.
