I'll vote with a "maybe".
On one hand, I think the whole concept of the movie star characters in Call of the Dead kinda cheapens Zombies' overall story and immersion. (I wonder if the whole thing was just for money or if they seriously just thought it was a good concept. I think it would have been better if they were all in character more, and they could have kept it a bit more zombies relevant...) But on the other hand, I sort of view it as just a joke map. If you look at it seriously it seems ridiculous... but it is a fun map. Challenging, but fun.
I love the level design. It felt like Der Riese meets Shi No Numa (my favorite) to me. I'm all for bigger zombies maps. I'm anxious to see what they do next.
