Aside from that, lets get down to the naked truth about the entertainment industry. The are a business. That's why they are called an industry. And to my knowledge, a business is only out for one thing, money. If that money is somehow connected to your tastes or anything else, they will use whateverr means they can to exploit that and reel you in hook, line, and sinker. It's happened to everybody on this board at least once in their lives. Some i'm sure more than they'd care to admit. Now that lead to...
When most of us on this board first saw star wars, we were pretty young. I wasn't even born when the first one came out. I saw it when it was re-released with ESB. As such, when you are young, you are very impressionable. Everything makes a mark on you because you are still absorbing information without filtering any of it. As you grow older, you develop filters. these come about due to experiences that you've had in your life, mainly negative ones. Anyway, you embraced star wars and still hold it dear because of this. It left a very strong impression on you, and now that your older, the new ones have not. In reality, it partly has to do with this and partly with personaly tastes.
All in all, shirmaa is right. You do need to grow up and that's what change is an indicator of, that you've grown up.
