No burp jokes, no poop jokes, no fart jokes, no comedy aliens hitting themselves in the head jokes.
No wars between faceless disposable characters I don't care about.
Less alien characters, Yoda, Jabba and Chewie were fine but I don't want tonnes of weird looking creatures as main characters. Keep them in Cantina like scenes.
Less exposition, more plot driven action (I don't want some guy over to one side of a computer generated room explaining why action scene 23 is going to spawn in five minutes time and form the basis for a computer game and a lego range).
Women as main characters who do things other than prepare lunch, stand around wearing a range of clothes to justify 12 action figures or sit and talk slowly.
Robots that stand up for their rights even when the good guys threaten to get their pet monkey to pull them to bits.
