I won't be seeing it, so I won't be walking out, but omigod does "I Know Who Killed Me" sound like one dreadful movie! It is at 8% right now on rottentomatoes.com
You know it's bad when reviewers write comments like this:
I wish I could say one nice thing about the movie, but even my old stand by of, “At least, it started on time,” doesn’t apply here. After a 20 minute delay in starting the movie, I had to assume the projector was taking an ethical stand and refusing to be party to the heinous act of showing this movie to people who were forced to pay for it.
Ack!
