I saw those clips the other day. Wasn't smart to have people who have no idea how to play the game, or games in general, show the game off. There is already enough bad PR surrounding the game, this doesn't help. It's time for them to show off the multiplayer.
Those complaining about the graphics need to realize this game has never been about that. It's not why people enjoy playing Crackdown and never will be. Do you think people play Minecraft because it looks pretty? It's all about the gameplay and playing with friends. This is the same for Crackdown.
