I assume you already watched the first season when you are watching this and its better in almost every way, art is the same but the plot and its episodes and characterization are better in every way(the villains are also much better than previous seasons as threats), animation its on average better than the average episodes of last season but it doesn't have the really 2 good animated episodes of the last one. So despite all those improvements and more consistent narrative and an actual overarching plot its ruined by filler(meaning non relevant episodes) and the pacing goes to hell due to this since they geta lot, hence the low score, this story would be better if it had half of the episodes.

Its ending foreshadows the next season so unlike the previous season, this is more of an adventure continues ending.

So overall this season is okay for a kids show, its good episodes are above average by those standards but be prepared for lots of non plot relevant episodes to drag this down.
