This episode was basically a rehash of 'The Flame Pokemon-athon' but with random Pokemon. I really don't see how this is learning anything at the school other than adapting to random Pokemon that they got. Overall the Pokemon School arc had great potential but ended up being a very lackluster set of episodes.
Yeah, I find myself disappointed by this entire block of episodes, actually. In the end, they just felt like a cheap way to introduce another 'Masamune'-type character like in AG. Ash always needs that friendly rival, etc etc.
Some more music: When the instructors instructed the students what the course would look like, Route 27 played. Also, this marks the first time that the R/B/Y Gym Theme has been used since the Johto league (started playing directly after Jessie's Kabaurdon burrowed underground)
I thought the episode was really good actually. Magicarp, Kouhei, Spoink... :D
