Me, I don't mind the term "powerplay" that much. Things like that tend largely to pass over my head.
As regards the actual use... I hate more than anything the idea that the batting team have any choice in one of the powerplays. I actually think that, used well, the system has the potential to aid the fielding, not batting, side more than the 15-over rule does. But many captains fail to do that.
