I see.
I thought Batman: Hush was really good. Kinda surprised that DC didn't save the story for a big screen adaptation. (Suppose the animated one could've been theatrical, too, with a bigger budget and all that). I really like Batman vs. Teenage Mutant Ninja Turtles, although I will concede there's noting really deep about it. While Justice League vs The Fatal Five feels more like an episode of the cartoon series it continues, I was engaged and really liked seeing Jessica Cruz being brought to life onscreen. The two '60s Batman movies were pretty good as continuations of the TV show. While uneven, Wonder Woman: Bloodlines had some good sequences and ideas, although I might admire it more for the premise then the execution. Mask of the Phantasm is, of course, a must see, but that was made long before DC's current's DTV series, so probably shouldn't count.
Kinda forgot how few I'd actually seen (although the only one coming to mind that I've never wanted to re-see was Assault on Arkham). Need to get around to Gods and Monsters and Red Son when I get the chance.
Wasn't super familiar with the movies you were citing, so I guess I misunderstood what you were looking for.
