The fourth, and mercifully final movie in the Wishmaster series Wishmaster: The Prophecy Fulfilled is a pointless romp through nowhereville where the Djinn gets his third wish! This should mean bringing forth the legions of Djinn into the human world, and royally screwing it. However, (blog post) instead he goes on an adventure to learn human love in the worst supernatural dating game you can imagine. Why? Because they never bothered to check (blog post) the previous movies to make sure the key point in the plot of this one wasn't completely fucking stupid.
