It's sad how much they screwed up with the dub music in this ep.
Replacing the Regi music in the Pikachu-falls-off-a-cliff part was already a big mistake,
but the BGM in the next scene, where Ash climbs up that cliff on the rope just takes the cake.
This scene was supposed to be emotional, almost dramatic may I say. And what do the dubbers do? They put in some adventurer wannabe music from the second movie, which was completely out of place. Well done <.<
About the episode itself, it was very good. How ironic that Team Rocket, who had caused Pikachu's illness, were also the ones who healed it. I liked that^^
Strangely, my favorite scene in this episode was a totally insignificant one; the one where Jessie made some soliloquies, unsure whether she should attack or not. I don't know why but I had to laugh about this.
