I don't think you need to worry about stupidity like Scary Movie 4 coming to any theme park any time soon. The intent is to be relevant in today's market trying to appeal to the most over-entertained generation in human history.
Since only the tastes of a couple demographics matter anymore, the appreciation of history side of things is being disregarded in favor of said desire for relevancy. I don't really like it. I think it opens the door to extreme levels of dumbing down and overprocessing of both product and park guest. That's where WDW is heading & they'll charge more than ever for it. It's a sad reality, but that's what it is.
