Kingdom was never that good anyways and stole the thunder of its predecessor. Bear-y Tales was the OG and should of never been taken out. Even though I think it would of suffered the same fate as Kingdom anyways when it comes to the ride system. As much as I would of loved to have seen them do a Garner Holt edition of the ride. I'm very happy to accept the return of the IP since its Knott's underrated dark ride. Videos online of the old ride do not do the thing justice when it came to the lighting, animation, and etc. But I am happy that Rolly's pride and joy is back in any kind of way. It's actually accurate to the original from what I have seen and beautifully stands out on its own than trying to duplicate the original exact.
That and it has Rolly Crump's blessing and even his Chris (who worked on the original) is even helping with it! So there you go. As for the longivity, we'll have to wait and see. I think it dying is just hyperbolic at this time and I can tell you that what I see in that video is far more than what Iron Reef could wish it have. It also kinda tells you that it will be here for the foreseeable future. Hopefully, one day we can see things get added to it overtime like a figure or two. That would be cool!
