I pray to god it isn't, because if it is then it's going to be a big letdown because I have high expectations off this movie. The tokyo idea is a genius one and the clips they are showing look REALLY REALLY interesting.
Plus I heard that the whole "question" of whether Starfire and Robin's relationship is anything serious will finally going to be answered in this movie, and being a big Star/Robin fan, I hope it's going where I think it's going
.
The other reason this movie has to be good is that this will more or less be the last time we see the Titans in anything new. All DC toons are gone with the exception of The Batman and the new upcoming Legion of Superheroes show.
Shows usally "end" with movies, Batman:AS was the only show to get like 3 movies and I've heard crappy things from Superman's movie "Brainiac Attacks". However, The Batman's movie "Batman vs. Dracula" was AMAZING!
If they can make a DC toon movie that good, I'm hoping the same can go for Titans: Trouble in Tokyo.
