I never really got into anything from the DCAU other than Batman:TAS which I really do think is the greatest "kids" TV ever made because, if nothing else, it doesn't patronise its audience. Also, the animation is incredibly beautiful and the storytelling is almost always really strong.

Personally, I preferred Batman & Mr Freeze: Subzero to Mask of the Phantasm but, then again, Heart Of Ice is probably my favourite episode so that makes sense.
