No, YOU may have asked for something new. Everyone didn't. It's a personal opinion and everyone is entitled to them, if people want to hate then they can.

Infinity Ward released the trailer for their new zombies game mode and what do you expect people to do? People will judge it based on the trailer and what we know.

When the game is actually released maybe all of the hate opinions will change to positive energy and people will actually turn to like it. Hell, even I will like it after the game is released (and so far I really am not liking it).

Basically: You like the look of the new zombies mode based on the trailer and other info we have been told, and many others agree with you. Whereas, many people don't like it... And at the end of the day we can all express our opinions on if we do/don't like it based on the existing information.

It's like saying you shouldn't hate on a priminister going for election based on what he promises he can bring to the country & how we should vote for him and wait and see... LOL. I know you didn't mean it in that way but I get what you're saying, but apply the logic elsewhere and you'll see what I mean.
