YMMV: Mars Needs Moms
- Family-Unfriendly Aesop: Even lampshaded.
Gribble: I was a good kid. Followed orders, put my toys away. That's why they took her, because of me. What kind of message is that to send to a little kid?
- Inferred Holocaust: Oh, sure Milo saved his mother and got home but there's the small issue of the evil fascist regime that's been in power on Mars for decades. During which time they've been casually throwing baby males into the garbage to fend for themselves, training the females to be unquestioning enforcers, executing dissenters and murdering countless human women. All apparently carried out by Martian society at the whim of one individual's insanity. The past evil deeds and problems facing Mars are unlikely to be instantly solved by revealing society was built on a lie. Somewhat averted in that they have Gribble and Milo (and his mom) to guide them through the internet connection.
- Narm: After Milo wakes up his mother moments before being vaporized and she has a moment to realize what's going on, she lets out the whiniest, most awkward scream of terror imaginable.
- Nightmare Fuel: See here.
- Tear Jerker: The fate of Gribble's mother. Not to mention how distraught he was when he was telling Milo.
- Milo and his mother's argument before plot can even start. His mom shouts that she wishes she wouldn't be such a nagging mother to him, and Milo shouts that he wishes he didn't need a mother. She opens the door and simply looks at him with such utter shock, indicating that he's gone a bit too far, especially her hurt expression as she simply closes the door. You can even hear her sniffling if you listen closely.
- When Milo's helmet shatters, and he starts suffocating in space, his mother gives him her helmet so she can die in space instead, pulling a Heroic Sacrifice. Milo's crying and pleading for his mother not to die really brings this trope home. Luckily, Gribble managed to dig up the extra helmet that was meant for his mother.
- The Scrappy: In a movie full of Scrappies, Gribble is probably the character audiences hated the most.
- Uncanny Valley: As this trailer demonstrates, the movie easily surpassed The Polar Express in terms of creepiness. It doesn't help that they used an actual kid for the voice but based the motion capture off of Seth Green, hence the dissonance. And the baby Martians, oh man, those baby martians.
- Unfortunate Implications: A Something Awful review points out just how strictly this movie adheres to conservative family roles: the Martian women have assumed positions of power that have left them completely unable to care for Martian children (as there's no way someone can hold a full-time, influential job and be a loving mother at the same time), the Martian men have become effete layabouts as a result. The movie concludes that Martian children will only truly thrive when raised by a mommy and daddy, and anything other than the traditional nuclear family isn't capable of raising children.
- Not helped by the fact that Milo only describes his mom as doing domestic things, like vacuuming, doing laundry and taking care of him.
- What Do You Mean, It's for Kids?:
- The hype makes it sounds like a comedy, but the kidnapped mothers get their brains drained before being vaporized. No wonder Gribble didn't want to tell Milo the truth behind why he's on Mars.
- Milo's mom almost gets vaporized to provide memories for the new generation of Nanny-Bots, then Milo gets shot in the foot with a laser and suffers not from excessive blood loss from GETTING SHOT, but will now die because his helmet broke, and then his mom pulls a Heroic Sacrifice to save him, dooming her. This also spawns some Fridge Brilliance.
