I have pretty mixed feelings on the original, which boil down to River being a deeply irritating Troubled Mary Sue, but the rest of it being pretty decent. I reckon that taking Whedon out might not be that bad a thing: his style can be good, but it can also get a bit tedious. Also, as Parson points out, the original episodes were shown in the wrong order and the show never really had an opportunity to develop itself. While it was never terribly strong stuff, a more toned-down, Disney-friendly Firefly would be a bit weak. I wonder if other shows have more-or-less done what it would do by now.
