My experience with the dyed-in-the-wool Trekkie/Fan is that the quality of the film will make no difference whatsoever, and every bit of what you predict will occur. The popularity will be escalating until the earth implodes. The marketability will be a phenomena. Money will flow like cheap wine. Lucas will be hoisted upon shoulders, stalked by adoring fans, and heralded a master of the big screen. Light sabers will be wielded. Capes will swirl. Boots will march.
But I still say the movie sucked. And I was in a big theater full of other people who said the movie sucked. Cuz it sucked. It was bad. I liked the others. This one was poor. It was bad. Ew. Icky. Blah. Based on Lucas' statement that he'll never make another, I can only say he probably knows it, too. Plus, I for one, am delighted he isn't making another one like THAT one, anyway.
