Lets start with what we know.
This was the first Batman series using 100% computer generated graphics. At the time, DC claimed that they had solved the problem of "textureless plasticy" characters.
Turns out they were wrong. The series bombed and if you do the research you will see that the timeslot was changed to a new slot so obscure that, as one reviewer wrote at the time, said "it was almost as though they wanted as few children as possible to see it."
What we also know is that, after its demise, the show has become a cult hit of sorts. This is because, as strange as the animation is, the writing and script were first-rate. Novel, original clever. Lots of WOW factor.
And the voice actors? Brilliant.
As I said, a hard show to review.
