The Wisdom of Friends was such an overall success that the creators decided that it should the final movie to seal the deal. But because the fans begged endlessly for another movie, Universal gave in and released a horrible excuse for a movie. Even the original movie is better than the 14th one, and that's saying a lot. It had horrible graphics, voice actors, character design, and an overall grainy quality. The only thing that saved the first movie from total failure was the Sharptooth. So yeah, Universal couldn't care less about LBT anymore, and only released a 14th movie to appease the beggars.
Why is the Wisdom of Friends considered the worst movie of the LBT franchise?
(Wow, what a contradiction to the answer above my question!)
