Anyway, does anyone know if where that BGM came from during the flashback scene? Like, if it was from a movie or anything?
You mean when it was showing all the scenes of Aipom/Ambipom? It sounds like it came from the Movie 9 soundtrack. It had the same choral style as much of the other music from the movie, as well as the background.
As for me, I was surprised when I first found out that Ambipom was leaving. However, unlike others who are extremely ****** off about it, I'm not. I mean, yes, it would've been nice to have her stick around with the Contests and all. However, you also must remember that Ambipom had just discovered something new that she was enjoying. As well, she was being commended by a top player. Ambipom has already done a lot in this saga. I mean, she took part in three Gym battles (two with Ash, one with Dawn), four Contests (two of which resulted ultimately in a Dawn win), as well as being traded and evolving. That's a lot more focus than people are realizing.
As well, I see a big difference between this and the Ash/Primeape release episode. For one, Primeape won the competition it entered, even though it should have not done that well, given lack of experience and the opponents. Dawn and Ambipom got far, but they lost. Ambipom leaving is trying to fulfill potential that is seen within her. Primeape left because it was already the champion, and really couldn't stick around with Ash.
For me, I think that it was something that the writers could have avoided doing, but it's not something that I'm majorly upset about.
As for the episode itself, I found it quite entertaining. Of course, they did add much for dramatic effect (flaming ping pong balls and breaking paddles), but it was nothing too bad. There were a few amusing moments, such as Brock and James interactions and Ash grabbing a fan. However, this was about Dawn and Ambipom, as it should be. I find that it was a much better episode than people are giving it credit for.
