- Alternate Character Interpretation:
- Although it's widely accepted that Kim fell for Ron when she finally realized that the right guy was next to her all along (supported by the lyrics of "Could It Be?"), there were others who argued that she only got together with Ron because she went On the Rebound after her previous relationship went sour. The debate faded when the series was Un-Cancelled and kept Kim and Ron together as a couple to the very end.
- When Kim smirks after kicking Shego into Drakken's tower, electrocuting her and sending her down with it. It came as a shock to some audiences who saw it as a case of Disproportionate Retribution where Kim violently overreacted to a verbal taunt about something that was entirely Drakken's doing, after the heroes won and all Shego was doing was trying to flee the scene (never mind that Shego tried to kidnap Nakasumi and played her part in Eric's Faked Kidnapping). Others saw it as a case of Beware the Nice Ones, in which Kim refused to let Shego walk free given her involvement in the whole matter since Ron had already cornered Drakken (who Kim had actually punched in the face earlier), and decided to end their longtime bitter rivalry (for now) in a way that made it clear that there are some lines you just don't cross; you never, EVER mess with Kim Possible's heart.
- Catharsis Factor: For everyone who has shipped Kim and Ron from the beginning, and going through agonizing moments of Ship Tease, them getting a Relationship Upgrade and The Big Damn Kiss was long overdue, but worth waiting for. Especially considering the heartbreak they both go through in the movie.
- Critical Dissonance: It was a bigger hit with fans than critics, but still well received overall.
- Fashion-Victim Villain: After taking over Bueno Nacho, Drakken trades his lab coat for a business suit — a light blue business suit with a silly-looking print pattern.
- Harsher in Hindsight: In light of many high profile Domestic Abuse cases (such as Chris Brown and Rihanna, and Johnny Depp and Amber Heard), and several Gaslighting victims being Driven to Suicide, Eric's abuse of Kim during their short relationship, and her reaction to the reveal bringing her to the Despair Event Horizon, makes him a bigger monster in hindsight.
- Hilarious in Hindsight:
- A redheaded Disney heroine falls head over heels for a seemingly perfect guy, only for him to crush her with a Wham Line revealing he was Evil All Along, prompting her to hook up with the blond guy whose affection she'd been completely oblivious to. Worked so well, Disney decided to use it again.
- The "No on 65" Easter Egg sticker on Ron's mirror becomes funny since the show did eventually get more than 65 episodes produced.
- Ho Yay: Kim and Shego's fight is infamous amongst fans for this, in particular the part where Kim smirks at Shego before kicking her off.
- Memetic Mutation:
- The phrase "Out there, in here" has become synonymous with Kim and Ron's romance among the fans.
- In that same scene, fans have given lighthearted mockery of Rufus' good (his Big Damn Heroes moment) and bad timing. explanation
- Money-Making Shot: The Big Damn Kiss of Kim and Ron at the end of the movie is definitely the scene that everyone who watches the movie wants to see.
- Moral Event Horizon: 901, aka, Eric crosses this line when he gaslights Kim into ignoring Wade, the first sign that she's in an abusive relationship. 901 solidifies this when he stages a Faked Kidnapping, and sadistically tazzes Kim into unconsciousness, showing him off as a Jerk with a Heart of Jerk Bastard Boyfriend.
- Signature Line: The aforementioned "Out there, in here" line.
- Signature Scene:
- The aforementioned Money-Making Shot, where Kim and Ron's Dance of Romance ends in The Big Damn Kiss, the very last shot in the movie before the credits. It's so iconic that it was added to the opening sequence of the fourth season.
- The scene where Kim kicks Shego in the radio tower. It's so shocking to see Kim reacting so violently. The part where she smirks in the rain sas added into season 4's intro.
- Tough Act to Follow: When the show was given a Post-Script Season, Bob and Mark admitted they had to tread lightly with the renewed season.
- The Woobie:
- Kim. She can't get a date for the upcoming prom, and Bonnie's words really tap in into her insecurities about her self-image, leading her to think that no one wants to go out with someone who beats up goons on TV. When she finally finds someone who will date her, who also happens to check off every mark for being the perfect guy for her, he turned out to be a heartless synthodrone and The Mole, which broke her heart and made her finally give up.
- Ron when Kim starts dating Eric. He quickly finds himself in a very dark place when he's Locked Out of the Loop and can only watch as the girl he realizes he loves has her heart completely set on someone else, which causes some friction between them as he fears he's going to completely lose the person who means everything to him. Although Ron decides to go to prom to confess his feelings to her, he backs out thinking it'll backfire and ruin their friendship and finds himself alone on prom night. In spite of this, Ron doesn't turn his back on her and continues to support Kim as Just Friends, and his loyalty pays off in the end.
