What movie sequel do you not want to see?

I just heard about Blade Runner 2. I really hate this; I think they should just leave it as a standalone piece with its delightful ambiguity. I understand it's a commercial rather than artistic decision, and the studio are entitled to do as they wish, but I have no interest in seeing a sequel to Blade Runner.

So what sequel is the one you did not want to see, yet they made it anyway? And what sequel do you dread appearing from the Hollywood recycling machine?
