Most of the "box sets" are TV series seasons collected into one set (Star Trek: Original Series, Heroes, Samllville, Sopranos, etc.) or film runs (Matrix collection, Die Hard(s), Mission Impossible(s) & collected Harry Potters). They tend to include extra bonus feature disks, but from my experience, are a good buy.
I agrre that all I really want is the best version of the film, without all the extra crap. That is why I have such a problem with Blu. They, more than the HD DVD's, seem to want to put all these "gee wiz" features that only serve to make the newest releases impossible to play without a new firmware upgrade.....
Best,
