Worst movie you watched because a BTVS/ATS actor or actress was in it?
Basically, what the subject^ says (though I had to shorten it because it wouldn't all fit):
What was the worst movie you watched because an actor or actress who you liked from Buffy the Vampire Slayer (or Angel) was in it?
Without a doubt, for me, it was (and still remains) Cruel Intentions 2.
