I liked seeing subtitles for when the Pokemon on the island talked and the scenes on the roller coaster car were pretty entertaining. 8/10
Good episode especially with the subtitles. My favorite part was when we saw Giovanni getting mad that his theme park was ruined.
I liked watching Pikachu, Fushigidane, Hitokage, Zenigame, and the Rocket-dan's Pokemon getting into all sorts of adventures on the island, and the bar scene itself was surreal. The island's mechanical Pokemon were frightening, and I liked how Musashi and Kojirou tried calling Sakaki to ask for assistance.
I loved that the cast's Pokemon themselves got an episode all to themselves: I liked to see what they really thought of Ash and their trainers. Loved the end, with the whole train chase and the mechanical Pokemon crashing into each other.
