Yeah I saw this last week! When I initially heard about it I thought "What's with them making all these oddly themed batman movies, like steampunk etc" - then I watched this trailer and thought "okay, this one I wouldn't mind seeing"
I watched this night. The animation was phenomenal (though I don't know how Harley, Catwoman and Poison Ivy managed to keep from toppling forward given their ample endowments) and that was the highlight of the movie. The plot was bat-shit crazy (excuse the pun) and, yes, kept getting crazier. It was almost a Power Rangers movie except it was cast with Batman and his crew plus a handful of super-villains. I'll always compare any Batman-related media to The Animated Series and Arkham City.
