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.
Alternate Character Interpretation: Many viewers consider Professor Bomba to be a terrible parent who place more value on his obsession than on his wife and daughter. Then MK comes to accept that he was right, yet Bomba never learns a moral lesson about his neglectful behavior, making him appear all the more unpleasant.
Base Breakers: Mub and Grub are either really funny or really annoying to most people.
"There's a protagonist grieving over her mother's recent death, and a brilliant but scatterbrainedfather who loves his child but isn't the strong parental figure she desperately needs. There's a hidden world akin to Alice's Wonderland that the inquisitive heroine explores. There are beleaguered good guys that she joins in a war against bad guys that represent chaos and decay; their leader is a funny despot with a European accent. There's a mythology that will be fulfilled when good guys take a fragile pod on a journey toward a prophesied end. There's a young warrior with whom the heroine forms a flirtatious friendship. There's a tough older warrior who mentors the younger warrior. There are comic sidekicks, and a beautiful forest queen who utters platitudes about the cycles of life and then dies."
Draco in Leather Pants: Dagda, who has barely been seen in clips and trailers, already has a small female following on Tumblr.
Ho Yay: Jokingly mentioned by MK in regards to Nod and Ronin, but it's obvious she's not the only one who caught it.
Mood Whiplash: MK finds her father when she sneaks back into her home. It's quite a Tear Jerker, as he's looking at a picture of his family with a completely heartbroken look on his face. And then, he opens his mouth, and in slow motion says, "I'm sorry, MK..." This launches the scene straight into narm.
One-Scene Wonder: Pitbull's character, Bufo, only appears in two scenes and was never mentioned or seen again. There isa bullfrog skeleton, labeled as Bufo Americanus in the Creative Closing Credits. Considering how we left Bufo (having accidentally insulted Mandrake's recently deceased son) ...
Paranoia Fuel: So, there's a race of little people that are experts at hiding. You're a renouned scientist, and you know they're there. But the little folk think you're stupid, and decide to play mind games with you, to the point where you're an obsessed wreck that's lost his job and his marriage chasing after things that they know are real, and you know are real, but they won't let anybody else know are real.
Unfortunate Implications: The ending. MK's father has no job (and no future, given that his credibility is shot) and is shown to do things like put food next to pesticide and try to make sandwiches with moldy bread. Their house is described by a taxi driver as "termites holding hands." MK is still 17, and yet gives no sign that she is enrolled in high school or college. However, it's a-okay for the two to make up and live together at the end, with no apparent changes. As long as they can talk with their tiny friends, who needs to pay bills/buy food/get an education? Plus, now everyone will think BOTH of them are crazy, unless they want to reveal the forest people's secret.
There's also the running notion that if the pod opens in moonlight it'll be a new forest queen but if the pod opens in darkness it'll be a dark prince. Not exactly the most balanced gender role logic given the implication if it's male it'll be bad and good if female. This is totally excluding the whole "light decides gender" implication which is a whole other ball of yarn.
