Did you pick up on this theme during your playthroughs of the games?
Nope what I usually do is catch a few Pokemon and battle the gym leaders and then after beating the game, I begin to think of the theme of Pokemon Black and White
Do you think they were effective in putting this theme across?
Based on the theme that you listed above, I think they were effective in putting this theme across. I do believe that this is basically opposites
