The problem doesn't seem to be entertaining and satisfying guests that visit, indeed a very high percentage of them appear to love the experience. The issue seems to be the numbers of current guests aren't sufficient enough to satisfy Disney's profit margins. Disney have to shoulder much of the blame due not only to the pricing, but the advertising of this experience originally.
Unfortunately from the commercial they hid so much that the whole experience really didn't get across very well and that first impression stuck. You only have to look on here to see there's people whose only knowledge of it is what they glimpsed from the commercial and the subsequent backlash of negativity that brought, who believe that nobody likes it and that it offers next to nothing other than bingo and dancing. If you take any time at all to research it and watch videos of it, you'll see why it's loved so much by so many who've been. Sadly many won't do that (which is fair enough) and yet come on here talking about how awful it is purely based on these preconceptions, perpetuating the myth that it's not an enjoyable experience.
