Lord Vader orders you to not reboot and tarnish his film.
Really, George Lucas is the perfect embodiment of the whole remake/sequel craze. He sacrificed his own artistic integrity to give us the Star Wars prequels, which were mostly pointless exercises in destroying the original films with wooden dialogue and performances set against a bunch of expensive special effects, including one abominable Gungan (the best of the three prequels, Revenge of the Sith, did not feature any dialogue from Jar-Jar. Coincidence?). And thanks in part to his shamelessness, we have the summer of 2010, in which nearly every movie is based on an existing property of some sort.
However, I should thank Lucas. As a result of both his positive and negative contributions to cinema, I am greatly anticipating Inception this weekend (of course, Christopher Nolan, Ellen Page, and Marion Cotillard have a lot to do with that as well).
