1) If you insult the intelligence of the fans by having the 'comic relief' be yet more obvious 'jokes' from C3PO (this is such a drag, and so on), or include Jar Jar Binks or anything similar in any way, I shall personally hurl all of you into a trash compactor. And no droid friends on the outside to help you this time. You're gonna get tentacle f%$ked like a hentai chick then crushed into powder. The original trilogy had Han Solo, that sarcasm was funny for kids but he had more depth than a simple comic relief character. That's how you tell a story, with characters that aren't one-trick-ponies.
2) Flashy special effects do not a film make. Never forget that. God knows a lot of the world has recently.
3) Leave the truly absurd ideas for crappy teen fanfics. Luke doesn't go door to door trying to recruit Jedi as a Kenobi's Witness, there are no angsty school scenes, and so help me God if there is a musical scene anywhere in any Star Wars film I'm gonna fucking Force Choke you. Let's see you sing with blocked airways, bitches.
4) Just because the actor is some pretty boy who looks good on the posters the teen girls will be fapping to, it doesn't give him any right to desecrate the films with acting on par with a dead slug sliding down a window being passed off as alive because it's still moving. Again, refer to the original trilogy. Han Solo vs Anakin Skywalker. No fucking contest.
5) If you absolutely MUST have stupid moments in there for fans to spot, make it like the cantina scene. The alien with the see-through head, and so on. Have Donald, Goofy and Sora visible in the background just for a few frames of the movie, blink and you'll miss it stuff. Don't do a Pokemon and thrust it right in our faces all the damn time (think about how many NPC's in pokemon only talk about how great pokemon is).
6) Don't do what Final Fantasy did. At this point in a series, you owe it to the fans to give them what they want. This is not the time to break from what works, get lazy, or fuck it up in any other regard. Listen to the fans. They know what makes a good Star Wars film. Well, some of them do. Some of them are just trolls, refer to previous comments about crappy teen fanfics for details. But seriously, stick with what made the original trilogy work. It's widely accepted that the prequels licked balls compared to the originals.
7) And finally, to reiterate as it's jolly fucking important, NO JAR JAR BINKS. So help me, if I have to sit through another racial stereotype that adds damn near nothing to the plot, has few lines or actions of consequence, and was added in only as comic relief when they're far from funny, I shall dedicate the rest of my life to the research of laser technology so that one day I can build a real lightsaber, simply so I hack your bollocks off with it.
