While the animation is not always gorgeously smooth, that series holds up soooo well in every other way. Fun and full of sparks for imagination. Just enough consistent characterization and character growth balanced with the action. And lots of hilarious Frank Welker unicorn voice. Myeehh!!

I'll join you in downvote land -

And then after it gets good, it gets pretty repetitive.

There are some great characters and moments but there's a lot of the same tone and type of action for large sequences of episodes, even after it is thought by some to get beyond the procedural format.
