IMO Celtic Fyre is a super high-quality show for a theme park (except for the horrible bar song segment). BGW definitely needs to keep an Irish dancing show of the same quality.
However, the same basic show (yes they have made small tweaks but nothing significant) running for as long as this has run is just stale. There is so much different Irish-style music that would freshen up this show. A new story line. But all of that costs $ to reproduce. I realize that Irish dancing choreography is limited, but this show is definitely due for a change.
Using the summer show for this season is 100% a budget cutting move. It sounds like the only changes are vocalist-related and they didn't even bother to re-choreography the dancers for this Christmas show. This is disappointing. They were advertising the show as "New." It's definitely not.
BGW entertainment has went through a significant decline in recent years. Examples. The elimination of full production "Miracles" with its low-production replacements, the elimination of the orchestra in "Gloria" changing to "Unto Us". Replacing full production "Britmania" with subcontracted sideshows. Replacing (although it was absolutely horrible) "Fiends" with a DJ show. All of these changes have less entertainers, and less production. Pure budget cuts. Just about anything in the Teatro di San Marco in the recent years has been purely low budget.
It's obvious how SEAS runs their company more by budget cutting than trying to attract people with a top quality day. The staggered park opening, outright ride closure without replacement (DarKastle) and reduced operating hours are prime examples of this.
I used to feel there wasn't enough time in a day to experience the entertainment and attractions at BGW. This was mainly because of the show quality and there were several shows worth seeing multiple times. Now I feel like there are only 1 or 2 shows worth seeing on a visit and seeing them once is enough. Everything can be done in a day with time left over.
I think anymore BGW and KD are in a "race to the bottom" instead of trying to outdo each other. One park is doing what the other is getting away with. KD cutting their hours back like Busch, Busch cutting their entertainment back like KD. KD closing major rides without replacement like Busch.
At least BGW is the "most beautiful park in the world" with the weed-filled Colonial Pipeline running right through the center lol.
