The plot also leaves something to be desired, the Court of Owls feel underused and the zombie ninjas come across as an excuse to have an enemy that Batman can kill. The Dollmaker and his cyborg orphans in the opening are way darker and more interesting than anything else in the film, setting up a false tone that's not delivered upon. Also, if the Court has been around for so long, how come we haven't seen them before? If they had only just come to Gotham, that would be one thing, but it's clearly implied that the Court killed Thomas and Martha Wayne and their secret base is huge and very high-tech, clearly not something they threw up overnight. I don't know, it just seems that with an asylum-full of iconic villains, alien dictators and international environmentalist ninja assassins in his rogue's gallery, Batman doesn't need a mashup of the Illuminati and the Eyes Wide Shut orgy-goers to fight.
I will admit that the fights in Batman Vs Robin are pretty nice, they'd make good scenarios for Batman miniatures game or SS4, especially when Batman, Nightwing and Alfred are defending Wayne manor from an assault by ninja zombies. Naturally, I want to do something like this now, but I can't justify building an entire Batcave... yet. If, like me, you can stream this or find it on Netflix, it's worth a watch; better than Son of Batman, but not as good as Under the Red Hood. Better game fodder than narrative.
