I've tried a bunch over the last bit but mostly duds...KC and his sunshine band have just spoiled us...perhaps they can try for an alternate series (preferably in another city/country)

Here is my opinion on audiodramas.

Good
Were alive
Leviathan (this might end up in bad pile if season 1 doesn't get better)

Undecided:
Age of zombies- story line has potential (1yr postzombie apocalypse) but the background music is louder then the vocals many times, and the levels hurt my eardrums. Many story lines = ambitious or destined to fail

Brave men run- kids with super powers, sound quality is better then most. But kinda teenage drama/maturity

The failed cities - post apocalypse religious/gang wars.*Interesting concept*

Byron chronicles - sometimes really good but many times really bad. Technically solid but story doesn't really suck you in.*

Earthcore- ehh...not great but I'm only 1 episode in...quality is worth a try

The sparkling dead- about to try it


Bad
Zombie nights
Dead Mech- really good start but zombies that use ironman like mechs...really?
Unleashed-*
The takeover
Fetdius
Infected
Contagion
Fried green zombies
You have dead on you- lame jokes with a lamer story lines*

Hopefully this is helpful
