Warner Bros., why?! You're better than this. We're already very excited for Batman: Arkham Knight, we don't need some awkward promotional video featuring celebrities like Neil Patrick Harris playing the game with forced reactions. Trust me, your game will do plenty fine on its own.
I don't know about you, but I've never made "pew pew" noises while playing a game. I'll never understand why publishers feel the need to make their actors do the same in these types of videos.
So awkward.
