That's true, if they had kept it just about Hollows it would kind of run stale after awhile...the direction he took it introduced us to many characters, many story elements...at most, if had stayed at where it was at the start of the series, then it should only be a 25 episode max show (or for manga chapters, anywhere from 70 to 108 chapters).
