- Awesome Music: The credits has "Heart Drive", a rap-metal duet between Alexa Vega and Bobby Edner with a bitchin' chiptune-inspired synth hook sprinkled on top. It's so cheesy it goes around to being awesome.
- Big-Lipped Alligator Moment: The appearance of the "real Guy". To clarify, he just suddenly shows up, gives an inspirational speech... then he gets severely curb-stomped, booting him out of the game. He is never talked about again.
- Ensemble Dark Horse: The Beta Testers, Demetra and the "real" Guy.
- Ham and Cheese: Sylvester Stallone as the Toymaker. He is clearly having the time of his life as a madman evil video game programmer who talks to holograms of himself as a hippie, a general and a mad scientist. Him sporadically shouting his dialogue helps.
- Hilarious in Hindsight:
- Juni being referred to, within a video game, as "the Guy".
- Juni at one point is controlling a giant yellow robot.
- Robert Rodriguez later went on to direct Alita: Battle Angel, which is co-written by Laeta Kalogridis, who will be creating live-action tv-show adaptation of Sword Art Online, a light novel series that gets frequent comparisons with this film.
- Memetic Mutation:
- The sheer lunacy of "The Guy" being built up in Game Over only to appear and be booted immediately afterwards. Elijah Wood playing him for basically 2 minutes makes it more surreal.
- "DID SOMEBODY RING THE DINKSTER?!"
- Comparing the final battle, in which Carmen and Juni call in every character from the entire series for backup, to the climax of Avengers: Endgame. Multiple videos have been made syncing this scene with "Portals", the music that plays during the Endgame scene.
- "Gonna tell my kids this was Sword Art Online." or any comment comparing the two.
- That the armor suits look like Iron Man suits.
- One-Scene Wonder: Elijah Wood's cameo as "The Guy", who lasts for all of sixty seconds upon his reveal.
- Padding: Elijah Wood's cameo as "The Guy", who lasts for all of sixty seconds upon his reveal.
- Retroactive Recognition: The girl that "owns" the water park at the beginning is played by Selena Gomez.
- Sequelitis: With copious amounts of Special Effect Failure, Dull Surprise acting, and a disjointed plot, critics and audiences both disliked this entry.
- So Bad, It's Good: Some consider it the best movie in the series for being the most unintentionally hilarious.
- Special Effect Failure: The 3D is very poorly done, barely resembling 3D at all. Understandable, seeing as this movie came out when the advent of 3D was still trying to get on its feet, and the movie itself was filmed using a primitive version of James Cameron's 3D camera system.
- The greenscreening is also incredibly blatant, especially during the fight scene at the end of the movie.
- They Wasted a Perfectly Good Character: The Programmers are established as crucial to the creation of the game and as especially powerful enemies being able to knock people back to level one and cost Juni a life just by poking his chest. Further, they're a malicious force that is completely human in contrast to the mindless monsters in the game. They're only used for a quick gag and chased away in the short scene they show up for.
- They Wasted a Perfectly Good Plot: The film might have been a little better if it had put more focus on Grandpa getting to feel young and powerful again, instead of summing his Character Development up in a little speech at the end.
- Took the Bad Film Seriously: Ricardo Montalbán. The scenes between him and Toymaker were easily the best of the film.
- Toy Ship: Juni and Demetra.
- WTH, Casting Agency?: Ricardo Montalban reprises his role as Grandpa Valentin; most fans lament that this film wound up being the late actor's final live-action role.
- WTH, Costuming Department?: Some of the battle suits are quite laughable. "The Guy" in particular looks absolutely hysterical for a supposed badass.
