One of last season's best new shows didn't start out so hot—so you may not have caught it. But Fox's little watched "Dollhouse" ended up kind of blowing our minds, and now it's miraculously back for a second season.

But you shouldn't let a little thing like not ever watching it before keep you from tuning in now. The heady concept is easily understood once you break down the facts. And we've got all the key points you need to be fully prepared for this month's premiere.

The second season of "Dollhouse" premieres Friday, September 25, at 9 p.m. ET/PT on FOX.
