Just watched the dub episode, and yep, I was sad.
Most part of the episode was boring. Team Rocket's attempt to steal Pokémon normally makes me smile but this time, I wanted them to go away... They didn't have their place in this episode as much as the normal ones.
The only real part I liked of the episode was when they arrived in Kanto. Iris's goal, her wishes and Cilan's passion for fishing made me realized that they were right to go on and continue their dreams, just like Dawn and Brock.
The train station scene was pretty sad. Although I was disapointed, emotion-wise. I think it was lacking. My eyes became wet only when the train door closed and when I saw Iris and Cilan go away. I loved them so much.
Overall, the episode could have been done way better than that. It wasn't that good, honestly, and the BW trio deserved more.
Goodbye, you two. Best wishes, and see you soon!
