The problem with Chima wasn't that it tried to be like Ninjago, the problem with Chima was that it had good elements but it didn't know how to use them well
Look, the plot makes wants you to think these animal tribes are in war, but you can't buy that because they only bother to show the reasons about why the Lions and Crocodiles want to kill each other, but they didn't do the same for the other tribes. The Eagles and Gorillas are with the Lions and the Wolves and the Ravens are with the Crocodiles because that's how it seems in the promotional material. if you want to put several sides in a war you have to give to all of them a reason about why they are in the side they are and why they want to kill the other side(s)
Laval is, easily, the worst character of all. I mean, he's the protagonist, but the least he has is character devlopment. There are moments that the writers could've taken to make him look like a good son, friend and warrior, someone who wants the best for the tribes of his world, but instead of that, the writers just kept him as the annoying, stupid and so bland character throught the entire series. He makes so stupid choices that you can justify them saying that he does them because the writers need the story to continue
This series has the most annoying perfomace of voices that I've ever heard in a kids show. There are serious moments where the voices sound more like if they're trying to make a comic gag, which ruins the feeling of the moment.
The villains are pretty pathetic as well, starting with a female crocodile who uses a flower to control his brother and rule Chima (cliché), going through a scorpion that I don't know why he wants all the chi for himself (another cliché) and finishing with a sabertooth who wants to freeze all the land without a justified reason.
This show has a problem using comedy. Seriously, most of the jokes more than making you laugh, they will make you close your eyes of embarrassment and you'll thanks to yourself for not seeing this with someone else (Assuming that you plan to watch this alone)
I'd talk about the side character but all of them are just too annoying and bland that is not woth it
And to end, most of the story is bad written. The first season is boring and lame, the second looks like if the writers didn't know what to do with it and the third is the only one wich I think is nearly good... well, decent. And the last episodes were the only ones that tried to catch my attention,those were the only ones that kept me awake to see what was happening. The rest, aside to be boring, they don't wake up the desire to watch them again
All in all, Legends Of Chima was a faild attempt to replace Ninjago. The only good things I can say about Chima is that it had a good animation, soundtracks and theme song, but that's all, everything else stinks. I wouldn't recommend you to watch this, but if you wanna pass cringe, well do it
