Look, I only want an honest-to-goodness continuation of "Ash vs. Evil Dead." No prequels, no sidequels, no remakes, no reboots, no re-imaginings. Just the ongoing adventures of Ash, Kelly, and Pablo. The story they have now is fine; more than fine. The worst thing they can do right now is overhaul the Evil Dead series again, and again, and again. The franchise will look more battered and worn-out than the Terminator movies.
I'd suggest creating an animated show of some kind, like others have mentioned here. Hell, the sky would be the limit for a post-apocalyptic landscape in the animated realm, where they wouldn't need to worry about craft services, location scouting, etc. Or if Bruce Campbell is really dead-set against ever playing Ash again, launch a comic book version of AvsED season 4 (much like Buffy Season 8, or Angel Season 6). Then Bruce wouldn't even have to get behind a microphone to record Ash's voice.
