WesternAnimation It's worth a shot
I must admit, after watching the first episode of RC 9 GN, I innitially wanted to give up, but forced myself to watch further episodes. Around about episode ten, I started falling for the show and Season 2 seems to have a higher quality than the previous season, both on the visual and narrative side.
Basically, what I'm saying, is that the show may seem wonk at first, but it's the cheese and so bruce. Give it a go, watch a few episodes and I think, even if you don't like the show, you'll at least appreciate the opening sequence, which is so beautifully animated.
WesternAnimation As of Episode 23, a great piece of television
When I first heard of Randy Cunningham 9th Grade Ninja I was not impressed. The premise is basically Danny Phantom by way of American Dragon aesthetics, and when those shows were new the concept was still old. But I was completely wrong.
The show's title is also it's summary, but I'll give more detail. For 800 years Norrisville has been protected by a masked hero known as the Ninja. But unknown to the public, every four years a new hero is selected to don the mask and fight off the forces of Evil.
The strength of RC9GN is not in originality, what makes RC9GN great is execution. RC9GN was a good student, learning from cartoons who came before and using what made them work. A quick but creative transformation that can be extended but also easily be done in seconds, fluid and intense animation during show's many fights, a great sense of comedic timing, and characters (heroes and villains) that are well designed, likable, fallible, and consistent. Randy grows and learns, and the villains he fights are both hilarious and threatening. The mythos is revealed piece by piece at a slow but steady pace that feels like the characters are learning more about the past. RC9GN is like the best parts of all previous high school super hero cartoons were cherry picked and used effectively.
But RC9GN isn't devoid of creative thought. Instead of struggling to learn on his own or having some kind of mentor figure, Randy has the Ninjanomicon, a mystical book that provides knowledge and hints. Instead of just reading it Randy can literally dive into the book, his mind leaving his body while he enters a world drawn in a traditional Japanese style. But this is a textbook, and an ancient one at that, so it's covered in margin doodles and the important bits are highlighted, tips from ninjas before interacting with the Japanese art as well as popping up in combat creates this really neat feel.
Not to say the show is perfect. The villains are hilarious but completely static, it can indulge is some pretty juvenile humor that really doesn't work, and every once in a while that character animation becomes incredibly stiff and boring. Randy grows and changes but the world around him is very constant at this point, no sense of consequences or change in the world at large.
But these are small complaints, so do yourself a favor and watch RC9GN.
WesternAnimation It's an over all good series
When I first heard about this show, I thought "Oh great, another Danny Phantom". Then, I watched the show, and was pleasantly surprised. The show has heart, humor, and soul to it. It also has potential. I'm definitely going to stick around and see it grow into an awesome, epic series.
WesternAnimation Good... Except for howard.
I remember really, really liking this series as a kid, and I still do, but... Howard is easily the worst character in the show. His jerkassery is made even worse by the fact that whenever Randy tries anything, the universe conspires to screw him over while Howard repeatedly endangers the lives of citizens because Randy isn't hanging out with him enough or treating him nicely enough. Maybe it's a case of them being great buddies off screen, but that doesn't matter if he's completely insufferable most of the time. However, good animations, cool monster designs, nice simple plot that isn't idiotically simple, and the fight scenes are really great. Does suffer from some pretty crappy "Out of order" episodes in the first season, which is very egregious considering the arcs are only 1-2 episodes long usually. Unironically would have been improved if all the Howard stuff was majorly cut down in favor of adding more time and budget to the fight scenes, or even romance subplot stuff.
