Firefly is a completely awesome series... that it was cancelled is testament to the state of the TV industry and the reality TV zombies that watch it. The series combined so many great elements it's no wonder it has such a fiercely loyal fanbase. It is a quality, quality show in so many respects. Great script, great acting, great character and a great setting. Who cares if it's not all new and 100% original, it's the end result that counts.
My understanding is that the whole initial premise was "cowboys in space". Trouble, I think Whedon thought he was being original. Actually the idea is so old-hat that a man named H L Gold wrote an editorial criticising it. In 1950.
I'm going to go against the common grain here and say I thought it was a very average series. It had the odd good idea (the Chinese was a nice touch - particularly they never translated it), but too many cliches. Fillon was mis-cast (as anyone who saw the last series of Buffy will tell you, he makes a better villain than hero). The main thing is that he simply doesn't have the charisma to make you understand why his crew would follow him anywhere. The character repartee took a long time to get going too - and yet this is what Whedon is most famous for.
That said, I enjoyed it a lot more the second time I watched it.
And the Reavers were just silly - they simply made no logical sense: they act like crazed zombies, but can run (albeit badly) and fly spaceships.

Fillion was perfectly cast imo... he added an element to that role that I think few other actors could have pulled off. He managed to be cold, ruthless, rogueish and yet honourable all at the same time... he made the character damn likeable, and it worked. Plus his line delivery was spot on in both tone and timing.
ALso, Reavers are not meant to be Zombies in space... they are completely depraved and psychotic humans who while undoubtedly insane, still retain intelligence and cunning enough to have some rudimentary society. DON't forget, all of these charactes grew up around spaceships and technology... it will be second nature to many of them, no matter their warped state of minds.
The repartee is there, it just isn't very good. There's no feeling that several of these people have been together for years.
As for not following Mal, I think you are misunderstanding me? The plot requires them to all do so, but the series (and Fillon - but it's not entirely his fault) fails to demonstrate why.
Not only did some of them fight with Mal in the war, but others stay with him simply because it he has never let them down... and that they can trust himto not only act fairly and not screw them over, but generally find good places to scavenge, and broker good deals with trader when selling their bootleg gear. I imagine that sort of character was hard to find in a dog-eat-dog universe where everyone wants to either arrest you, screw you over, or eat you.
