Enterprise cancelled?

Last February 2, 2005, UPN and Paramount announced that Star Trek: Enterprise will be canceled. I just read about it today, and it made me feel sad. Why is it that when the story gets interesting, they decide it will be canceled? I hope this will not be the end of the franchise.
