^I vote for Resident Evil as well..... of course I still want a Classic Monster attraction also. Can't help it, I'm greedy.
Honestly, TWD isn't exactly dark subject matter... its just zombies (which is really the only thing the attraction would consist of, just like at HHN). And you'd be shooting said zombies... same thing as the RE attraction, only with less variety of things to shoot at unlike RE, which has Lickers, Tyrants, Nemesis etc along with zombies. Besides, guests will complain about anything and everything. The park can't rely on family-friendly content alone.... When I was at Citywalk the other night seeing Krampus, I was wearing my HHN hoodie from this year and a little kid (had to be no older than 6 or 7 years old) behind me pointed it out saying it was their favorite show. -shrugs-
