Where to start? ...I can't say I'm very impressed by this whole ranger business. Funny how there just happened to be pokémon randomly loitering about for her to use, eh? It would have been funny if none were available and they had to waste time looking around the forest for some.
The plot was essentially ripped-off from the fourth movie - Serebii is in a dangerous situation, teleports itself to another time, is weak from using too much energy, Satoshi-tachi nurse it back to health, it's stolen, then saved, and goes back to whenever it was in the first place. Not very original.
And "Cycling Road"... is a blasphemy. It's bad enough that the writers refuse to include anything from the original Kanto, but when they take something that actually was and completely screw it over, it's just revolting.
Honestly, Kojirou-tachi were the only part I really enjoyed in this episode. I actually chuckled when they were trapped in the vines and Soonansu popped out and squashed Musashi. They seem to have a bad time with vines, don't they? They could have used a Kabigon to help eat them away and clear the spring. Oh, wait...
And I officially love Manene now. It was hilarious when he was imitating Kojirou struggling with Sabonea.
