Don't listen to deathwing702, he doesn't understand the movie AT ALL! It was actually extremely satisfying and it tide up some loose ends for the original series. Sure, there were a few moments that could have been changed or cut out, but that's if you're being picky. I appreciated the fact that it focused more on Kaiba and not so much on Yugi or the Pharaoh. I mean seriously, Who isn't tired of seeing Yugi always taking up the spotlight. It's refreshing to see Kaiba step up as a dominant character for once while not getting his dolt handed to him in a duel by Yugi. Unlike deathwing702's obtuse opinion, the ending was exceptional. If you don't agree, then you failed to understand who Kaiba is as a person and character. Go watch it in English DUB of course, you won't be disappointed if you were a fan of the Original Yu-Gi-Oh series.
