Since I had no idea it was coming to the US, I kind of obtained the Japanese version in an erm... less than savory fashion. And watched it with my brother. And we were both impressed. It's probably not going to knock your socks off, but unlike pretty much every other video game movie, it feels like it fits the source material while managing to justify a movie format. Easily the best video game movie I've seen (which isn't saying much...)
Oh, this is an animated movie, not a game! That's cool, I was pleasantly unaware of its existence in the first place. I will try to catch up with the games in the mean time.
@heliumsky I THINK it takes place between the 4th and 5th games in the series. The games however are pretty self-contained plot-wise so I wouldn't worry too much.
@-JKR- I teared up at the end of the game too. Shhh.
