Awful animation and a uninteresting story...tho the animation is probably responsible for that. Flat, immobile or deformed faces don't really convey much. Also hard not to notice a mouth not aligning with dialogue at all. If I wanted to watch crappy anime or Hanna Barbara that's what I'd do.
Hush as a character is non-existent. There's no story telling here, just a sequence of events. The Batman and Catwoman storyline is the only thing of substance.
At least it was 'free' with DCU. I'll try to plow through and finish it eventually.
