Toy Story 2, Cars 2, Toy Story 3, Kung Fu Panda 2...
Blue Sky Disney: Titled...:Don't get me wrong. I'm not saying I'd love to have a great title and a really crappy film. I'm just asking why we can't have both? While I love John Lasseter's attention to detail focusing on the films his Emeryville studio makes, I just have to ask why they can't spend a day or two trying to come up with a title to give it other than a number.
Reminds me of that golden age of the 80s when everything had to name itself "Something : The Movie" (as if people were paying 6.50 to see something other than a movie in a movie theater), like Transformers and Robotech (among many others).
Spaceballs, of course, rode that trend to a decent joke in the film.
