I am as big of a purist there is when it comes to WDW.
I am overjoyed that TWDC isn't scrapping the bears and is improving/replacing animatronics. Hopefully, the bears will be around for another 50 years. And, I am open to change with attractions, but I do not like the direction of including songs from different Disney movies into the bears show.
I would far, far prefer new original music throughout the entire show along with the new story. Pay real artists -- authentic bluegrass and country musicians -- to score an entire new show. It really isn't that hard. All TWDC needs to do is send a few executives to Nashville and listen to artists performing at the bars and find some young, talented songwriters to build and pen an entirely new story.
If that makes me a hater, then Amen.
