I went to Kings Island last week and was able to get two rides with very minimal waiting.
I never experienced the original ride, my hook was the show.
I really enjoyed both rides, and liked how they "de-fleshed out the characters." (From my perspective from the show they are static vs dynamic).
I think Hilda's personality came through most of all in the headliners. Garbonzo in the cannon was a nice surprise. Sir Pretzel was a nice addition.
I like that they kept some of the elements from Boo Blasters.
They flashlights were surprisingly fun for the ghost notes.
The smell of roses was a nice surprise.
On both of my rides, there was a brief stoppage, not sure if that was to allow for the turntable to stop for rider assistance, or a technical problem but even the stoppages were "themed" with the overhead announcement.
I was very impressed and look forward to riding again.
