There probably should've been "standard writers' standards" beyond "what the plot requires," you're right. The stickler in me is bothered deeply by these stretches of Trek tech, to be honest. At the same time, I just dropped almost $80 to take my family to see STID in IMAX 3BD on Friday, and I want to be entertained, dammmmmittttt! So, WTF about transporters. It's all hocum, anyway. At best, I don't want my wife to walk out and say, "Well, there's two hours out of my life." And she won't give a rat's ass about transwarp beaming, and a lot of other people won't either. In fact, if it speeds the movie up, she'll probably be all for it.
