Why are there so many Zombies these days?

 I am a little late with todays comic but I watched the third Batman movie(again) the past two to three hours so I'd advise you not to take a fight with me right now! I must say, the second time watching this movie it loses a lot of the problems I had with it, the characters I didn't like the first time watching this weren't actually so bad when you got enough time to think about them and follow them with a little more knowledge and the characters who were good the first time around were just as awesome this time. One thing I have to ask everyone who watched this movie is this though, why the fuck does the nuclear REACTOR(it's not intended to be a bomb) have a friggin timer on it that says when it's gonna blow up? Yeah Bruce Wayne knew that the thing COULD explode but he didn't intend that for the thing. -adios,D.
