I'm not too fussed, I mean it's sad to see the only 'original' Pirates go, but then you have to remember our Pirates is the total opposite of the original, so it's not like it's Walt's vision in the first place, the Imagineers created something much more different for Paris. This isn't so much changing what Walt wanted (
www..), but it is changing the original 'different' vision for the ride.
Saying that, the AA's in the others are very good indeed, and will add a whole new, fresh level of show to the ride, they're not too intrusive in the grand scheme of things, yes there are a few lines in the treasure room which means we'll probably lose the 'dead men tell no tales' whisperings in the background, but I can live with that if it brings a ride back to it's former glory and popularity!
Long and short of it, it's nice to see some investment back into an original star attraction, but at the same time I don't see it taking too much of the original ride atmosphere away. If anything I'm interested to see how they'll fit him into the ride as the scenes are in a totally different order - Davy Jones appears in the caverns at the start of the WDW version, we have a Bayou, so maybe on that first journey up the waterfall, that certainly is one of the more 'simple' areas currently?
Now if only they surprise us with that new mirror effect from HM for the end of PM!
