If you're on the fence about whether or not to watch this series, jump down, cancel your meetings, and grab a bag of chips to eat while you become enthralled in the greatest cartoon of all time and certainly on of the greatest shows ever made. The series delves deep into moral issues while maintaining an upbeat light hearted attitude. The characters are all people, they aren't just one dimensional figures put in for a corny laugh in a kids show. They all possess multiple sides that become developed as the series goes on and display feelings that everyone has experienced whether they are loss and confusion, or joy and love. Certain characters stick to a general set of emotions but are never bound to them, just as people in real life aren't always downtrodden or happy but fluctuate and are capable of change. The plot goes deeper than simply narrating a story. Sure this is a classic save the world plot but it's somehow believable. In addition to all of this, each episode brings with it a deeper meaning that holds true. The series builds on the back story of all of the characters to express these ideas and presents them seamlessly with the plot. The writers never forget to include a moral in each episode that leaves the viewer thinking at the end of each episode. Other issues are brought into the show as well, ranging from corruption and lies, to internal conflict and strife. All of this fits nicely into the plot without jutting out as a ragged edge.
While some shows clearly have a specific audience, this show goes beyond and appeals to everyone who watches young or old, and entertains them all. The show may have originally been made for kids, but that doesn't matter. It can teach everyone something. The humor at times can be a little too kiddy but usually it's circumstantial or slapstick, not blatant stupidity. Also, because this show was meant to run on a kid's network, no one dies some horrid death like in Game of Thrones or some war movie. In fact people dying at all in the series is very rare. The bottom line is that it doesn't matter the about intended audience but rather that the show is great for all ages.
The animation for the series is top notch with movements being fluid and punctured by moments over the top expressions for emphasis. Some details are obviously computer generated but those moments are relatively sparse and always seem to be well placed.
Lastly, the show is more than just entertainment, it's a really good teacher. It makes the viewer think and wonder while engaging them the whole time in the action and plot of each episode. If at first the series seems slow or boring, just keep going and you'll see the depth of the show. As a word before you start watching, the first season is mainly to set up everything but still contains a lot of action and entertainment. The second and third seasons really take the series to the next level. Watch this show if you haven't. You will be glad you did.
