These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Flight of the Navigator
Awesome Music: Alan Sylvestri's score, if you like '80s instrumental synth stuff, at least.
This assumes the Trimaxions are cold and dispassionate themselves, and treat their drone ships like nothing but hardware. Why assume that? It's just as likely they'll be highly amused by the ship's new personality.
The Trimaxions may all be Mechanical Lifeforms like Max. Besides which, if they place so much importance on benignly studying biological lifeforms, they may also find the memories and experiences of other sentient species to be worthy of study.
Also consider Carolyn McAdams, Sarah Jessica Parker's character, and her likely future. It's pretty evident when David escapes that the higher-ups believed she helped him escape. At best, she likely underwent quite a bit of uncomfortable interrogation from various Three Letter Agencies. At worst, she was likely thrown into a cell for the rest of her life (at least up until time gets reset by David going back).
Nightmare Fuel: The time travel sequence is terrifying to watch when you're a kid.
They Changed It, Now It Sucks: After Max gets his data back, along with a good helping of David's personality, he makes continuous pop culture references and becomes a robotic Pee-Wee Herman. Many preferred original Max.
