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: Legend of the Guardians: The Owls of Ga'Hoole
Angst? What Angst?: When Soren and Eglantine reunites with their parents at the end, said parents don't seem to care at all that Kludd is missing, if they even notice.
While it wasn't made specifically for this film, The Host of Seraphim, played when Soren flies through the forest fire to ignite an oil lamp and destroy the fleck-based mechanism. And for the trailer we have Kings and Queens.
Genius Bonus: Digger, who speaks with an Australian accent like most of the band, becomes accepted as a guardian and therefore a soldier with the rest of the band at the end of the film. So in Aussie slang that would make him a Digger Digger. Who digs.
Nyra crosses it we she manipulates the above owl into her own Tykebomb. As for Metalbeak, trying to kill Ezylryb in front of Soren.
Nightmare Fuel: The movie is chock full of it, including: Allomere getting dragged off by vampire bats, the bats themselves, the Battle of the Ice Claws (Deleted Scene), Kludd falling into a raging fire while screaming in terror, the moonblinked owlets, etc. Really, it's surprising that the movie doesn't have a HONF page yet.
So Okay, It's Average: Despite the drop-dead gorgeous animation of the film, it suffers from the narrative trying to tell an epic story akin to Lord of the Rings in the span of roughly 90 minutes which ultimately just falls flat and leaves it as more of a Cliché Storm instead, which is probably why it's not remembered much.
Tastes Like Diabetes: The ending borders on this as it really goes its lengths to describe how perfect everything is, and how Soren and his friends were crowned Guardians over night even though it was earlier narrated how such a position took years to strive for.
Gilligan Cut: When the owls fly into the hailstorm over the Watchers Island. (If not conforming to the exact wording of the trope, it's at least in the spirit.)
What Do You Mean, It's for Kids?: A "PG"-rated film by Zack Snyder (the man who brought you 300 and Watchmen) with owls clawing and slashing each other apart, characters dying, bats tearing apart owls, impalements... And yet, it was aimed to kids. Then again, so were the books the movie adapts.
