Does it really need it?
Would The Walking Dead have been better on HBO?
Exactly. Everyone saying it would just be about nudity and cussing isn't looking at the whole story
Funding would be higher, which would have meant better actors (sorry some of these actors are really terrible) and overall would have just been better funded. Meaning better props, crew, would have had more time to film, and it would overall just be a cleaner, tighter show.
I love walking dead, I really do, but money almost always helps a show. You can just afford to do more.
