It reminded we why I don't really watch anime that much. One of the stories in the movie was your typical "guys just standing around talking" animes. How boring. Also, none of the stories felt all that well-written. I guess I've just been spoiled by The Animated Series and the other DC Animated Universe shows.
There's this one story in Gotham Knight in which kids tell different stories of Batman, each one with a drastically different version of Batman. Sound familiar? Yeah, TAS did it, too, and they did it much better.
The one with Deadshot was cool, I guess.
But all in all, I prefer the DCAU stories to this stuff. I mean, I spent the last three days watching as many episodes of Justice League as I can, and the writing in those shows is just awesome. And the animation, while simpler, is better...'cause when people talk, they don't usually just stand around. >=[ Also, they don't make Bruce Wayne look like Light Yagami.
I think the Special Edition of Gotham Knight comes with a few episodes of the TAS (including the original kids' stories one), so at least the people who buy that version will get some awesome animated Batman goodness. :P
While I guess Gotham Knight wasn't really bad, it just pales in comparison to the other animated Batman offerings.
Let's hope the Dark Knight doesn't disappoint either. Maybe I should lay off watching DCAU for a while. It's just soooooooo good!
