When is a complete series not a complete series?

[dvandom]

When, as is the case with Big O, the second season is called an entirely different series (Big O II). So, if you were hoping to get all of Big O on the "Complete Series Collection" coming out tomorrow, you'll be a tad disappointed. Big O II comes out in August, as another "Complete Series" set. (And yes, I know some people on my flist knew this months ago.)
