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 show does not sit well with fans of ThunderCats (2011). The fans will tear you apart if you say that Legends of Chima isn't a rip-off of that show.
Fans of Ninjago produced their own Backdraft, since Ninjago was originally intended to end the same year Chima began, causing many Ninjago fans to see Chima as a Replacement Scrappy. Even though LEGO has confirmed that Ninjago was not going to end, rabid Ninjago fans still think that Chima deserves to be cancelled.
LEGO fans in general have been put off by just how much LEGO is investing in this theme. Comics, a TV series, a video game, an MMO, and an entire section of LEGOLAND Florida is only just scratching the surface. It feels like LEGO is trying to shove Chima down the throats of its fans while neglecting its other themes, which naturally leads to a lot of complaining on message boards.
Narm: The dialogue and story can be surprisingly clever, but some of the voice acting can be downright painful. Then there is the dialogue that isn't clever AND is narmy.
Whenever anyone in the show says the word "Chi", it sounds like they're about to say "cheese". The best example would be the scene where Laval confronts Cragger and says, "Drop the Chi, swamp creature!", which sounds just like, "Drop the cheese, womp creature!" Unfortunately, since Chi is integral to the plot, characters talk about it often, making it impossible to take it seriously when it sounds like they're talking about cheese all the time.
Iron Woobie: Crooler sort of qualifies. Take one look at her backstory and tell me that she can't be emotionally damaged now. Then observe her actions. Not once does she give up on dethroning her brother.
Before it was announced that Ninjago would return in 2014, many Ninjago fans saw the entire Chima theme and TV show as a Replacement Scrappy for Ninjago.
There are fans of ThunderCats who feel this way because the main character of the show is a lion prince with the same color armor and hair as Lion-O.
What an Idiot: Cragger cut the rope that was being used to save his parents because he thinks he can lift up a giant crocodile tank with his bare hands.
After being trapped at the bottom of the chasm with his wife, Crominus assures her that he has the utmost confidence in Cragger knowing that the lions are not at fault and holding no hard feelings against them. Mere minutes earlier, Crominus had declared war on the lions because Cragger fired a croc-signal, and when Cragger tried to explain that it was an accident, Crominus replied, "I can't take that chance!" and declared war anyway.
