"Batman: Mystery of the Batwoman"
This one's easily my favourite out of the animated Bat-films of the DCAU I've seen thus far. I adore how it kept us guessing who Batwoman was, and just when it was looking to be one suspect, we see something pointing in an entirely different direction.
My only gripe is that it reveals to the audience who she is before Batman figures it out. I'd much rather have Batman put the peices together first, then letting us see it.
But a fantastic film none-the-less. The cast were just gold , and I have to give it up to the writers on this one, minus my wee gripe. Golden.
I've now finsished the Batman animated series entirely, with all movies. Now it's on to Justice League and Batman Beyond!
