7. Sci-Fi Apocalypse In Two Short Episodes - Dollhouse, "Epitaph One" & "Epitaph Two"
Dollhouse may not be quite as well loved as Joss Whedon's other shows, and while that might be because of a lack of coherent storytelling or a convincing lead for much of its run, it's certainly not for a lack of cool or interesting ideas. The premise itself pretty much explains exactly why the show never made it past its second season (and even that was a minor miracle): a secret, extremely powerful organisation wipes the minds of pretty young things and implants them with new personalities to do things like become dominatrixes and assassinate people. That's weird enough already, but just wait until you see the finales for both seasons - "Epitaph One" and "Epitaph Two" - which turn the whole show into a post-apocalyptic wasteland and act as a disconnected two-parter that's actually way more effective than the series' nominal finale. Set ten years in the future of the show, it sees much of the cast return, some with radical physical differences (except Eliza Dushku, who still looks 29 ten years from now), exploring the ruins of the Dollhouse and trying to find a cure for the mind-wiping 'disease' that's plagued the world for the better part of the decade. It's a 'throw everything at the wall' approach to ending a show, which is exactly why it works. The Epitaphs don't hold anything back; there are emotional goodbyes and surprise deaths aplenty, and it gives the show a more appropriate and kick-ass farewell than most fans thought Dollhouse would ever get.
