Granted, I did find it a bit too predictable. I mean, c'mon, it was almost certain the Dawn was gonna win. Well, at least in the aspect that the whole concept is cliche to begin with...
meh, au moins elle utilisait un peu de qualité. The VA at least made a mild effort to make it sound right.
All in all, I ended up enjoying it to some extent. Sure, it wasn't a high profile episode, but I found it enjoyable. The scenes with Brock and James were just perfect. I mean, I know that even in the lightest disguises Team Rocket is invisible, and the writers know this, so they pushed it as far as they could. Which made it even funnier.
There were some other neat mentions, like where Dawn remembers a key tip from Zoey. And, anybody surprised that Brock can make outfits really doesn't know him. Sure, it seems odd, but he had to know these things.
Piplup was quite literally "thrown" in for good measure. Oh yeah, they just had to have the penguin randomly appear. I don't remember you being in the first half of the episode...
Overall, not bad, great humor, and a decent lesson. Many nice references were made too.
