WB is putting themselves in a place where they definitely want to "compete" with Horror Nights. At least on the west coast. You don't pull out your big IP's in IT, Conjuring, Arkham Asylum and say you're just running a roadshow.
Now...with what happened to the backlot this year, we'll see how much longer that lasts, but I imagine they don't wanna just give up.
And that shall restrict the east coast as well unfortunately, just to keep on slight topic.
