Well it was better than Warm Bodies and Life After Beth...
Ok, this wasn't the greatest film ever made and not every joke exactly hits the spot, but it's better than some horror comedies I've seen in the last few years. The humour in stuff like Warm Bodies, Life After Beth and Dead Before Dawn, for example, was completely non-existent - so anyone saying that this is the worst comedy ever clearly hasn't seen any of those.
There probably isn't much more humour left to get from the zombie comedy genre, with Shaun of the Dead and Zombieland nailing it quite nicely already, but this was a valiant attempt at least for those wanting to see something new.
