I probably spent 5 minutes debating how many stars I should give this. =/ I have mixed emotions on this movie. The villain was horrible. And not horrible in a villainy sense. He was just plain sucktastic, and the whole basic idea behind this movie deviates from the original plot so much it isn't even funny. Yes, even in the Japanese version (though things do tend to make a little bit more sense in that one, and I would recommend finding a sub of it if you possibly can).
However, most people reading this will be viewing the English version, so I'll just stick to that. =3
The soundtrack was horrible, as is the soundtrack to the dubbed anime in general. The animation could have been better, due to the fact that they had waaay more than just one week to work on it, unlike the TV series episodes. But it wasn't the worst animation I've seen. It did look a bit pointier than usual, though. But the art is kind of pointy in general.
Now... I still recommend this for anybody who is a fan of the series. It's so horrible, it's great to mock and laugh at. But it also has some highly amusing quotes and character interactions. And some of the new monsters are pretty spiffy as well. It's so stupid it's hilarious, and the sheer hilarity of it is doubled for any fan who sees it.
Heck, I think I was rolling even in the first scene. XD
(Though, there was no excuse for them leaving out Bakura yet AGAIN. Poor kid never gets any screen time.)
