I dunno, Empok Nor struck me more as a serial killer/horror movie spoof of an episode more than your traditional O'brien Must Suffer episode. O'brien really didn't suffer that much. The random goldshirts and Nog were the ones who got it really. It was a fun change of pace, if not particularly inspired.
As for the angle? Yeah that was funny... I wish they'd just randomly change the angle more often to reflect it. I'd love to see the Enterprise flying by upside down or something just once.
