Joss Whedon speaks about Dollhouse:
Basically, the Network and I had different ideas about what the tone of the show would be. They bought something somewhat different than what I was selling them, which is not that uncommon in this business. Their desires were not surprising: up the stakes, make the episodes more stand-alone, stop talking about relationships and cut to the chase. Oh, and add a chase. That you can cut to. Nothing I hadn't heard before on my other shows (apparently my learning curve has no bendy part) but frustrating as hell given our circumstances - a pilot shot, scripts written, everybody marching together/gainfully employed... and then a shutdown. Glad I was for the breathing room, but it's hardly auspicious. So back into the writer cave I went, wondering why I put up with this when I can make literally dozens of dollars making internet movies.
I love the man, and the line "apparently my learning curve has no bendy part". Anyway, you can read the rest of the trials and tribulations of the show here.
