It feels like it's been forever since I last caught up with one of these DC direct-to-video animated films.
Lately they've mostly been following the same continuity, roughly following the New 52 Universe. The latest film to date is...
Justice League vs. Teen Titans!
I like seeing some of the titans in roughly the same art style as the Young Justice cartoon was. (Although Raven is so tiny!!)
Here's the trailer,
The JLA! The Titans! Trigon!!
This sounds fun enough!
