Dollhouse creator Joss Whedon has explained why NBC decided to cut the last episode, saying that it was very different from the rest of the season.

Episode 13, titled ‘Epitaph One’, should have aired in May however the only way to catch it now, is on the DVD boxset.

Whedon told Entertainment Weekly:

“So you will find out snippets of everything and all of nothing,” he said. “Every flashback answers something about where people are heading but brings up a lot more questions about where they end up or how they got there.

“It has a very different structure and feel from what we do on Dollhouse, so it would have been ridiculously startling to have aired it the week after the season finale as just this insane coda.”

He added: “And it is a little bit insane, except that we sort of follow everything through to its logical conclusion. As always, it’s logical to conclude that people are terrible and will try to destroy each other.”

Well if that isn’t enough of a reason to snap up the boxset as soon as it is released, I don’t know what is!
