They haven't really shown anything in the trailer besides a rather generic looking top down shooter. There don't really seem to be any interesting weapons, or interesting enemies, or interesting environments, or interesting story, or interesting gameplay, or interesting -- well, you get the picture.
Obviously this is only going by the trailer alone, but you know what? If the trailer didn't show anything interesting, then I can't really be blamed for having no interest in the game. If the game was anything more than shooting cops and civilians with a standard array of game weaponry, then they should probably have shown it off. And no, I don't care about the destructible environments that seem to get brought up often when discussing the game. Even though I absolutely love destruction in games, I love it more than virtually any other aspect, Hatred didn't really seem to show anything of note in that department either.
Edit: Okay, I had only seen the first trailer, so I decided to see if they had an actual game-play trailer. The destruction does look rather well done in the game-play trailer, now that they show it off a bit more, but it's not really enough to sell me the game.
On another note, I didn't think it was possible for anything to be more try-hard and edgy than the first trailer, that is, until I saw the second. It doesn't really bode well that the more I'm exposed to the protagonist's dialogue, the more I cringe with embarrassment for the writer and voice actor.
I'm still waiting for this game to pull a bait and switch, and turn out to be some profound work of art with a legitimate point to make. That would be rather hilarious.
