I think I watched this show in 2013 for the first time and have to say I did not like it very much. I continued to watch some of its episodes after that for few days but then got bored and stopped watching it.
There are few reasons why I stopped watching it:
1) the animation is very poor and not very interesting for an adult.
2) the story explanation is kind of slow, they take quite long to explain a single scene.
3) morals used are good but simple and only meant for children below or around 10 years of age and not for everyone.
All together I thing it is an awesome TV show for small kids but people above 15 years of age would probably not get attracted to this show.
