It's his dry and sober way of filming. But on the other hand, it was funny at several points. There were scenes, I did really laugh out hard and for quiete some time. If there weren't so many traces between the funny or laughing moments, it would have get a higher rating by me. A very ironical view on the zombie genre. Well, I was entertained and even though this movie is no real burner, I think it's still ok to watch. Bill Murray is great as ever. In my opinion the movie is better than most people rated.
