There's one thing about Star Wars that seems so obvious that perhaps most fans overlook it...it was never supposed to be a deep character study, or a realistic look at human characters. George Lucas himself has frequently mentioned that the original film, and the original trilogy were always supposed to be created in the vein a Saturday morning serial, or a glorified cartoon, while maintaining the grandiose elements of a modern myth. As a result...all six movies follow this structure. Dialogue is perhaps even the least important part in the movies by design because such shows are more about the visuals, and of course the sound effects and music, rather than the spoken word. Critics of the prequels attack the acting as "wooden" and the dialogue as "cliche"...but it's not as though George Lucas attempted to have good acting and failed...the characters are all a bit "off" of realistic by design. In short, it's supposed to be this way. The Original Trilogy has exactly the same amount of cheesy dialogue, bad acting ("I was going to go to Toshe Station to pick up some Power Converters!!!??") and over reliance on special effects yet they're seen as masterful while the technically superior prequels are panned.
While everyone is entitled to an opinion, it's interesting how Star Wars has been so widely successful...yet for completely different reasons that the director's intention. Fans want to see Harrison Ford shoot blasters, Chewie to growl, Boba Fett to hunt down the heroes again, and the droid zip around...but I'll bet all of that was always side dressing for the original directors. These films (though none perfect) were all designed to be visual pieces of music, a science-fiction opera if you will. I'm very curious if this new one will keep this tone. It might just make more "fans" happy...but it, and the fans, might have just missed the point all along. The Prequels achieved their goal; you don't have to enjoy the goal, but it's false to think they tried and failed.
