I wouldn't say it's a particularly fun read, but if you are interested enough to put in the effort it might be worth it for the perspective it provides of its particular place in history.

If you are interested in reading it, I would suggest the translation by Christopher S. Mackay: The Hammer of Witches: A Complete Translation of the Malleus Maleficarum. It does a good job of putting it into the proper context and it does provide some suggestions for further reading.
