Its not a good script at all, and you keep labeling everyone that does not like the new script as one of the "ALL CHANGE IS BAD!!!" complainers.
I am all for changes, when they are GOOD. For example, the recent changes to the Haunted Mansion - all tastefully done, all good.
This script is completely uninspired and the delivered by a person that does not fit the atmosphere at all. Its disgustingly sugary and sweet and robbed the attraction of any sort of cohesive theme.
Compare it to the narration on the WDW Railroad. That narration stays in character with the lands, rather than suggesting "This is Adventureland! Be sure to check out the hilarious show, The Enchanted Tiki Room Under New Management!" Iago: Squak! Thats right ya bird brains!" and follow Jack Sparrow as he searches for treasure on the new and improved Pirates of the Caribbean!", etc.
The train's narration gives you an overview of the lands, while staying cohesive with the theme of the lands and their attractions, without seeming like a blatant advertisement and nothing more.
One of the biggest reasons people loved the previous narration is because the announcements and chimes greatly enhanced the Tomorrowland atmosphere. TTA is Tomorrowland, and its shocking that the Imagineers didn't take that into consideration when creating this new narration. I wouldn't have minded that much if they had at least used an appropriate voice, for example, the female voice currently as you enter Space Mountain.
So please stop labeling everyone who doesn't like it as another whiner resistant to change. We hate it because its so incredibily generic a lot more than because we will miss hearing our cheesy jokes.
