I found Painkiller Jane to be incredibly derivative and totally lacking in originality. Then again, I only made it through the pilot and the first third of the second episode before I gave up.

I am generally good about giving shows a chance to find their "legs," but I just didn't see any potential at all in that series. Totally unoriginal premise, scenery-chewing acting, overly long sections of close-up violence...

Your mileage may vary, however.
