Skipping a few reviews. dp 56 and dp 57 are pretty much fillers.
I think this episode is the better of the two Pikachu interacts with other electric pokemon episodes, which is nice in a way b/c Luxray is the Sinnoh pokemon. But the main (and pretty much only) thing that makes this episode stand out for me is the scene where Ash talks to the young girl about the troubles he had with Pikachu when he was just starting out as trainer. I guess, sometimes I take that story for granted, and don't appreciate how special it really is. I know that Ash told the story in the Lucario movie as well, but here it shines through better as the young girl really envies the relationship Ash has with Pikachu (in the movie, the story just led to Ash getting into a fight). When she asks Ash how she should develop that type of bond with Luxray, Ash doesn't give her a straight answer, saying everyone is unique. But it is important to be friends with your pokemon and understand their troubles. That turns out to be just the answer the young girl needs, and she figures out herself how to do that (by hugging Luxray and bluntly asking it to be friends with her, to hers and Luxray's embarrassment). Watching Ash during that conversation and hearing the girl thanking Ash for listening to her troubles was just amazing; the scene also ends perfectly by shifting to Dawn and Brock, who smile at each other (it's perfect b/c I was smiling the same way when I first watched this). Brock knows about Ash's story already, but I think maybe for Dawn this is the first time; her delight and Brock's smile (as if to say he knew Ash would give the right advice) makes this another one of my favorite Ash and Dawn scenes.
Come to think of it, I remember something with a Raichu before in the Orange Islands....Yes, I see....Well, this scene isn't as unique as I would like to make it out to be. But it is a little different, in the way Ash's demeanor is. In the Orange Islands episode, he was showing off a little in that episode, as he was convinced he could make things right. Here, he's more natural, and only offers his advice when asked, and even then is not too forceful.
