I think a big difference with angry birds land is that usually we wouldn't see updates so regularly and in so much detail and there are times when the unfinished product hasn't looked great.
The park do care about how the park looks, that's clear from the recent effort we've seen from them trying to fix effects which have been broken since the Tussauds era (Inferno mist / Colossus pit) and I've no doubt when Angry Birds Land opens it will look good and whilst maybe not the area enthusiasts want, I think it will look good and most importantly the general public will like it, and I think saws a good example, disliked by a majority of enthusiasts but enjoyed by the vast majority of the general public which ultimately as a business is the most important thing.
