First off, we all know who's writing this; Mayor Lurkey, Chicken Little fanatic and hardly the biggest Cars fan in the world. But I am trying to make a point, so let's get past that.
I'm not too sure a Cars ride is a good idea. Yes, people like it, but I'm not sure it deserves a ride. Most rides in the Disneyland parks are either based on classic movies (Snow White) or not based on movies at all (in fact, they sometimes inspire movies, like POTC). Making a whole ride based on this movie is not, in my opinion, a good idea.
I've been thinking, and I've actually thought of other movies that might deserve rides; The Incredibles, The Rescuers, Treasure Planet (it would make a pretty cool ride, regardless of how popular the movie was) to name a few. Will people still remember Cars in a decade's time? Should the company really make a ride based on a movie that might, for all we know, just be a flash in the pan? This is just something that's been bothering me.
