Trinity Soul? That wasn't a P3 anime, dude.
You say you'll get the best from this film, the film which is likely to be 70-80 minutes long and skip most of the cool parts that were shown in the show.
And that true ending you're dying for? That's already in the show. Granted, it's exclusive to the DVD, but it's there.
Also, we don't deserve anything, one of our favourite games is getting a remake and we have a cool anime to go with it.
All this extra shit is neat if you're a fan of Persona 4, but it's overkill if you ask me.
