Look, Shimura wasn't bad here, but she had the misfortune of literally coming immediately after an episode that was among Iwane's best work.
I don't know why I laughed at such little things as Carnivine storing the pearl in its mouth followed by a "Good Boy" pat from James, or Muku.BIRD directing traffic outside the Pokemon Center (at least, that's the impression I got), or Piplup pouncing on the bird's back, causing it to shriek "KWHAKUH!". Maybe it's because the rest of this arc was so serious.
The ending was a bit of an anticlimax for a two-parter, as even though it was merely establishing a later plot point which will be huge, I wished for more of a battle, especially with Purugly and Skuntank. It was still a good arc, though. Did I mention how much I love Cyrus's cackle? He should, along with Yanmega and Conway, audition to play the next Joker.
A lot of people have suggested that J be hired to capture the pixies, and it's an idea I've never held anything against (in fact, I support it). With the mention at the end, it's looking as if she will be involved in Galactic's plot in some shape or form down the road.
EDIT: Slipped my mind earlier...no Milotic in sight! I will savor this victory for now, as I know it's only a matter of time before it invades our lives again.
