Pros:

This is a blast from the past from the first time that I ever saw a zombie.(witch,werewolf.ghost) madman?? oops sorry.

Cons:

depending on what mod you play: it may be a bit too much but....
An Easy fix. By a simple disable on those those particular mods, they do not show up at the time.

Conclusion:

Over all a well made mod that can most certainly add a sense of humor. Well done but can not be used all of the time for obvious reasons
