YMMV / Mars Needs Moms

  • Anvilicious: There is just nothing subtle about this movie, no wonder The Mysterious Mr. Enter said that Milo "is not a character, he is a walking plot device" who is just there to force the message in.
  • Audience-Alienating Premise: The movie's hilarious title is merely the tip of the iceberg, as it is actually much darker than one would be led to assume as it turns out the mothers in question are not just kidnapped, but vaporized for the sake of obtaining their knowledge in raising children; further reinforced by its rather depressing implications, as seen below. The notoriously offputting animation does nothing to help matters.
  • Bile Fascination: Its notoriously creepy animation and legendarily bad box office take have certainly made it this. And if that wasn't enough, reviews like those from The Mysterious Mr. Enter more than likely contributed as well.
  • 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?
  • Hilarious in Hindsight: Some of the aspects of Martian culture like how the males are discarded extremely similar to Gazorpazorp from Rick and Morty which is most likely a coincidence considering how the actual episode is intended to parody Zardoz.
  • 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.
  • 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 gender 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.
  • Unintentionally Unsympathetic: Milo's Establishing Character Moment of spitefully refusing to do his chores doesn't exactly do much to endear his character to the audience. That the rest of the intro has him continuing to be disobedient towards his obviously overworked mother doesn't help matters. It is obvious that they're supposed to be signs of missing his absent father, but the fact that he takes it out on his mother combined with him not really receiving any relatable character traits, and the fact that he just seems a bit too old to be throwing such tantrums just makes him look like a huge jerkass.
  • Visual Effects of Awesome: While the Motion Capture itself dips pretty deep into Uncanny Valley, the overall visuals are far more beautiful.
  • 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 is actually one of the reasons that the movie bombed at the box office, as despite being a kid's movie a lot of kids didn't want to see a movie where your mom would get kidnapped and killed.
  • The Woobie: Gribble may be a scrappy to most viewers, but he's still arguably the most sympathetic character in the whole film. To recap, he wasn't a naughty boy. He was a good lad, listened to his mom, did everything he was told to do. As it turns out that's why the Martians took her from Earth. Like Milo, he followed the Martians in an attempt to rescue his mother. Unlike Milo, he failed to save his mother. This left him alone on Mars. He's had no social contact with other humans for at least 20 years and has had to live with the burden of knowing that he is the reason his mom is gone. Is it any wonder he doesn't act like a normal human being? Chances are that he acts so comically in an attempt to mask the pain he feels.
