LOL, I saw it and, although I didn't want to like it since Kevin Conroy (Batman) and Clancy Brown (Lex Luthor) and Tom Daly (Superman) weren't reprising their roles from previous DC Universe pieces, I really did!
It was great! Awesome story, good visuals and animation and *sigh* good voice acting.
All in all, another awesome DC offering and I now eagerly await Batman: Under the Red Hood!
