The folks at Pixar swear that they are done with sequels. Well, at least, after “Toy Story 4” is released next month. After that we can look forward to original content, starting with Dan Scanlon’s “Onward.” Yes, it’s a movie about Elves but Ill give the toon company the benefit of the doubt, they have, after all, given us these past 15 years classics such as “WALL-E,” “Finding Nemo,” “Up!” “Ratatouille,” “The Incredibles,” and “Toy Story 3.”
