that trailer didn't show me anything besides girls not being moe kawaii, which is a plus. And yeah the only reason I didn't say something completely negative about DEEN is because of Zombie Desu Ka.
But let's remember that the studios that are doing Yamato 2199 were infamous for their low quality stuff before this show, and Yamato 2199 is really high quality. So every studio gets its chance. If anything has ever sounded like a game changer for this one, it's Pupa.
