I saw the trailer earlier on my PS4 just a minute ago, and I am still not interested. They already done another cinematic trailer with the first teaser. Odds are it's gonna play like Arkham in some fashion. My main reason for lack interests, is that is yet another, Superman has gone bad/evil/brainswashed storyline again. Those have been done to death already in all mediums. Come up with something more original or base it off one of the more popular SS storylines.
IMO this might be sequel to Arkham series, sharing similar aesthetic and character designs. Kinda make sense, since batman is no more and there's no one to come up with a contingency plan. Still, this is just an in-game cinematic, and we don't have any gameplay yet
