I haven't, but I have heard it's a good series. It simply raises all kinds of head-scratching questions about why the heck Cadmus or any other secret government group would put all the time and effort into doing such a thing. Superman clone? Doomsday Weapon? All sound stuff. Mecha-Animals, not so much. The DCAU isn't like the Brave and the Bold, and all of the more.. outlandish facets of the DCU don't really fit the tone. Shade-strange or Resurrection Man-strange fits the tone but that brand of strange doesn't. By tone, I mean how the DCAU is somewhat more "grounded" in a sense.
