Alright here are my thoughts and opinions categorized so as not to confuse your close-minded brains.

Campeign
Haven't played it yet. I can't say anything about it.

Zombies
Clearly you guys haven't played the game yet. You are constantly saying the same thing OVER AND OVER. "It's the same game". OBVIOUSLY. When you go to buy a sequal to any game you're expecting the same game, same storyline, same gameplay as the previous installment. Here's why and this may be a hard concept to grasp. It is the same game just part 2. :O. I know. Shocking as fuck. Now with this in mind think about zombies. It's the same thing, if treyarch changed anything of the gameplay everyone would call it confusing and stupid. But when you're more familiar with it, it's easier to play. Basically the premiss is you have an assortment of locations, and you start out at a transit center. Then you take a bus which is times to go around every 7 minutes. The bus takes you around the map to the different locations and you hold off wherever you want. I don't know about you but this would sound fun right off the bat. You get variety, mystery and entertainment. So there are also work benches at each location. which make different things. In order to make these things you have to find pieces scattered across the location and put them together on the work bench to create whatever that work bench entails. One of these things is a zombie sheild which works by hitting the zombies and then they go flying into the air. So, there's some more mystery. My point is this third of the game has so much entertainment packed into one little section. Once you get the hang of it, it's hours of fun.

Multiplayer
I will admit, the multiplayer is a little dry, I don't like it as much as zombies, but it is definitely NOT the same game. It's probably the best multiplayer experience of any call of duty game yet. You can have completely customizable classes. Here's my opinion on the multiplayer. It's like battlefield 3 but without the draggy, overly realistic graphics and movements, it's like Halo because it's a little more futuristic, and it's like MW3 in the way the guns are shaped and the way everything feels. There are so many opportunities as far as multiplayer and you shouldn't be steered wrong by these close-minded idiots.

Overall
3 games in 1. 3 amazing games all in 1. I hear they have professional writers and the composer from The Dark Knight in the campaign. I've witnessed customizability and action in the multiplayer. I've experienced the thrill of running from a line of zombies and turning around to shoot them all in the brains. Get this game, it's so worth the $60. You'll thank me later.
