Finally got around to watching this, and here is my impression on it:

The music video was very cheesy, however, I admit the episode...was done pretty well. It starts off very bad, as it goes out and lies that ash was still 10 years old and he had some really bad acting in the first half the episode. It almost seemed like he was just as stupid as he was when he started off his journey. I also hate how the episode focuses on Zekrom more than the other characters, which just adds more hatred on that pokemon. However, as bad as that may have seem, the visuals were even better than last generation. It seems that the colors are brighter and more saturated, and some of the FX in it look better than ever. The opening theme song was... like I expected, terribly bad. The music video's song was just cheesy, but this song was all around TERRIBLE. It almost seems like crossing freaking pokemon with the modern pop culture audience. TERRIBLE.

Aside those, so far the anime looks pretty good in Unova. With my gripes aside, I might actually start watching this more often, as it looks pretty damn promising.
