Heartwarming / Power Rangers Operation Overdrive

• The Ranger team accepting Mack after learning he's an android.
  • Before that, Spencer gives a great pep talk that points out Mack was never programmed with the emotions and bravery he's shown. He also admits, joking that he'd have to reprogram Mack if he told anyone, that he loves Mack as do his father and the other Rangers.
• The Heart of the Sea turns out to not be the first Corona Aurora jewel the rangers are looking for, they give it to Brownbeard, who gives them his lucky pearl in exchange, the real first jewel.
• The moment as Mack is held hostage by Flurious for the stones and tells the others to just let Flurious destroy him as "I'm not real." This follows his snapping on how he "knows I'm expendable" and that Hartford can just build another son. Without hesitation, Hartford gives up the stones with the rest of the team backing him. Mack is astounded as Hartford relates that he has always considered Mack his son and could never simply replace him as Mack thinks.
• When, after Mack's Heroic Sacrifice the Sentinel Knight appears and uses the shows MacGuffin to not only bring him back to life but help him to become human.
  • Prior to this, the entire team makes it clear that, even if Mack felt he was "just" a machine, they don't see him that way. Not only did they sacrifice the Corona Aurora jewels to save Mack's life, but after his sacrifice, when Hartford affirms that anything he built from Mack's damaged body would just be "something that looked like him", their genuine grief makes it clear that they want the real Mack and won't accept any kind of substitute.
  • Even better, the Knight's reason? When Hartford sadly says that Mack never had life and he was just a machine, the Knight retorts that Mack fought with true heart, proclaiming that it is impossible for him to have none, and crowns him with the Corona Aurora. Even people who hate Operation Overdrive have admitted that it's one of the few good moments.
  Ronny: You're alive!
  —>Mack: Yeah I'm alive. I can feel my heart racing at a mile a minute...wait. I can...I can feel my heart. Dad! I have a heart!
• While the Rangers might be...divisive this season, when they all leave to go back to their old lives, there are a few nice moments, particularly with Will saying that after learning the value of teamwork, he's going to build his own team to help keep people safe.
  • There's also the fact that during 'Once A Ranger' arc, while the other rangers resumed their old but self-driven activities, Will instead turned from a thief into a museum security guard, actually doing something that benefits others. Of course this can be mitigated with the fact that he eventually thought that wasn't fulfilling enough...
  • And the Adventure Continues for Mack and his father. In a Book Ends to the series, it ends with the both of them off on another archeological adventure.
