Joss Whedon is credited as the creator of Dollhouse, and was an Executive Producer, and the show featured many Whedon 'alumni', as well as his brother and sister-in-law writing many episodes.
However, Joss only directed the two season openers ("Ghost" and "Vows"), and only wrote those two stories and two others ("Man on the Street", and the season one conclusion, "Epitaph One").
This is much less than Firefly (wrote 5/14, directed 3/14), or Buffy (wrote 28/145, directed 22/145), but similar to Angel (wrote 11/111, directed 7/111).
How involved with Dollhouse was Joss Whedon? Was it mostly a project he created (with Dushku) and then left in the hands of others, returning for a couple of episodes? Or was he heavily involved, just not in the writing or directing?
