With horror, it can (and will, look at House of Horrors) become stale.
The Walking Dead Attraction, has had no signs of improving it's quality of life; or upgrading it with new scenes off of the later seasons.
I'd rather want Murdy to capitalize on a NBCUniversal Experience-esque attraction to replace it (as he did mention that it was one of the ideas for the venue a few day's ago (as I asked him about it..)); but I would suspect that dining would be higher on happening for that space than an actual attraction.
