I stopped watching sitcoms when I was a teenager, but I dunno, it seems to me like comparing RE characters to sitcom characters would be like comparing the military industrial complex to Greenpeace. RE and sitcoms seem to be diametrically opposed because survival horror is about discomfort and using wits to survive whilst sitcoms were designed to be therapeutic and make ordinary people feel good about their lackluster livelihoods.
Two very different worlds. ;}
