YMMV / Monsters vs. Aliens

Tropes for the movie

  • Big-Lipped Alligator Moment: The president's "eat lead!" bit, which interrupts the flow of the scene and doesn't really make sense in context. Which makes sense, since Colbert ad-libbed it.
    • Also, the entire Axel F scene, which is basically there because it's hilarious.
  • Cargo Ship: B.O.B./Green Jello. A match made in mixers.
  • Crazy Awesome: General Warmonger.
  • Crowning Music of Awesome: The orchestral cover of The B-52s' "Planet Claire'' that plays as the President prepares to make first contact.
  • Ensemble Darkhorse: Oh, there's a LIST for this one.
    • B.O.B. for the kids and the merchandise. Not really surprising he's the Kid-Appeal Character; he's the silliest looking monster, and the funniest character.
    • Dr. Cockroach hit it off with fangirls.
    • And there's the president, where every moment involving him is one of the most hilarious things you'll ever see.
    • Katie and Cuthbert, the One-Scene Wonder role reversal teens who encounter the aliens early in the movie.
  • Getting Crap Past the Radar: A very debatable instance. B.O.B. sees the tomato and desert topping that mutated into him as his parents. He consistently refers to the tomato, the thing that had something stuck into it, as the mother.
  • Hilarious in Hindsight: In one scene one of the President's advisors says: "In these situations I think to myself, what would Oprah Winfrey do?" Years later, Oprah would be briefly considered by the certain media publications like Buzz Feed to run for the 2020 Democratic party presidential nomination (and didn't end up running)
  • Ship-to-Ship Combat: The fandom is a bit split when it comes to who Susan gets paired with. Given the lack of Token Romance within the film, many tend to gravitate towards Dr. Cockroach/Susan since he takes an active role in trying to reduce her size and they seem to converse the most (also, they're the only two monsters who used to be human). But Link/Susan has its share of fans as well, considering that Link's whole deal is that he chases beautiful babes anyway. God help you if you're on the fence.
  • Ugly Cute: Pretty much all of the other monsters aside from Susan herself.
  • Uncanny Valley: The human characters all have realistically rendered skin which clashes with their stylized designs, making them come off as more creepy looking than the actual monsters.
  • Viewer Gender Confusion: Insectosaurus. The movie calls the monster a "he", but a behind-the-scenes book lists the monster as a female. This has lead to a Broken Base amongst the fans of the movie as to which is truly canon regarding the monster's gender.
  • What an Idiot!: Derek dumps Susan for the sake of his career without considering the worldwide fame their continued relationship would bring him, not to mention the millions of dollars in book deals and movie rights. Sure, he'd need a raincoat to have any hope of ever pleasing her, but it's still a very stupid decision from someone who's already been characterized as a selfish asshole. He does put things together, sort of, when he forgives her and offers to take her back at the end. Of course, mentioning that he was offered a network slot if he got an exclusive interview in the next sentence made Susan doubt his sincerity. Letting that detail slip only reinforced his stupidity.
    Susan: Are the cameras running, sweetie?
    Derek: Why, of course they are!
  • The Woobie:
    • Susan. After Derek dumps her, she looks so much like a kicked puppy.
    • The monsters, after they scare off the party.
    • Link. The poor guy gets his butt kicked several times during the battle against the robot probe, and even gets knocked out after it's already been defeated.
