I liked this episode, it felt more dynamic than most episodes of its caliber (as in take away Jessie catching Pumpkaboo and this would've been completely filler).
But it was very nice indeed.
There's really nothing I didn't like, outside of maybe Fletchling failing due to an ink spurt from Inkay but other than that, it was a fine episode.
I kind of liked it a little bit more than the Chespin capture episode. I guess it was fun but not over the top and it didn't feel like anything was shoved down our throat.
