This show is awesome! I know, people always say: "but it's LEGO, it can't be good, it's just a big commercial" well, let me tell you something, they're wrong! It is actually an amazing show! It also appeals to many teenagers and adults as well, not just little kids! Now lets get down to the review, acting first.
The voice acting in this show is VERY decent for a kids show. They get pretty good voice actors. (Vincent Tong, Kirby Morrow, Andrew Francis etc,) Some of the voice actors in this show are also from other very good shows, such as My Little Pony: Freindship Is Magic. I would rate the voice acting a 9/10.
Now we will be talking about story. The storyline for this show started off very simple, but then later grew bigger and more impressive. The shows original story was The First Spinjitzu Master created four golden weapons for the different elements: Fire, Lightning, Earth, and Ice. Then, the evil lord garmadon tried to take the golden weapons and the spinjitzu masters son, sensei Wu, had to gather four ninja to stop him. Sort of weak but later in the 4 & 5 seasons it some what expanded. I would rate the story a 6/10.
The music in this show is Excellent! It ranges from ancient sounding music to tech- sounding music. It has wonderful tunes with a lot of time and effort put into them. I would rate the music a 10/10.
Now it is time for the script. It has a very funny and cute script that makes me laugh, also has some heartfelt lines in there, maybe a few corny ones thrown in there. I would rate it a 8/10
I'm going to talk a little bit about the seasons, which includes some very personnel opinions, if you don't need to see it then skip ahead to the end.
My favourite season was the 5 one, "Possesion", it had a intriguing plot, awesome characters, and great humor, but I am also extremely fond of season 1 "Rise of the Snakes" because it is what got me into Ninjago, and season 4 "Tournement of Elements" because it just had a really "Ninjago Feeling" to it, and the characters and villains were amazing. The 2 & 3 seasons were good, but I think that they relied to much on action and cool vehicles, not as much humor, story, and character development. I'm giving it a 7/10 for the seasons and their layouts in general.
So that is my overall opinion on LEGO Ninjago! I think this show deserves a 9, especially compared to other new kids shows. Ninja-GO!
