Taking a look at the videos, while Pirates does have some impressive moments, I'm not exactly understanding the praise that this is one of the best Disney attractions/attractions period. I agree with JungleSkip that between Jack and Jones it's rather dead, and it does make the pacing rather odd/off. I'd love to ride it someday, but personally I don't think it's on the level of Indy, WDW's Tower of Terror or Spiderman. (Especially considering all three of those don't have dead spots in their pacing.)
As for Soarin' over the Horizon, admittedly this shocked me more then Jack's appearance in Pirates. It looks like a downgrade, it really does. I just rewatched a video of the original Soarin' and the differences in overall quality is shocking. With the original you get wonderful scenery with maybe a little CGI for some segments, meanwhile with this thing you get some great scenery, and others with a lot of CGI distractions, and in the case of the Taj Mahal segement...no sight of anything real in it.
