Saw the trailer, want to see the ending. And my bad. Movie 5's called 'Symbiosis,' not 'Union,' as was previously announced earlier this year. As for what I saw, seeing Tai's goggles on the ground totally makes me want to see what happened to him. We've never really seen Tai get extremely hurt, and I hope that's not the case. Also, what's going on with Kari in the clip is weird.
Should be a good film (which comes out September 30th, btw!!).
No shame in plugging here at Anime Forums. lol
