Quite frankly, I was disappointed with this boxset. Very disappointed. I mean, what happened? It's the same for all Diamond and Pearl/Battle Dimension/Battle Frontier boxsets or DVDs.
All around, the dubbing for these episodes was horrible. The script was terribly written -- it made the show sound like it was for an even younger age group than it is. Teens watch Pokemon and it was apparent that the scriptwriters either 1) didn't bother to keep us in mind or 2) simply aren't good scriptwriters.
I can even complain about the music. The music often didn't match up with a scene or was so low it was nearly inaudible.
What really got me, though, and what I think just completely ruined the entire boxset was the Voice Acting. To describe it in one word, I would have to say "unrealistic". Yes, it's a cartoon, but we all know that the characters should feel somewhat real. And I didn't get this at all from these characters. I felt nothing toward them and I didn't enjoy this product at all.
Don't buy it.
