I hope this is just something for the speculation bin, since if Orlando is getting this over SLoP, I will not be a happy camper.
I may be a animation nut, but for me in terms of films coming from major studios, Sing is right there with Ice Age: Collision Course in the "Do Not Care For" catagory. I really have no intrest in this film.
That brings up the next thing, that it would be some kind of show. When it comes to shows, be it live, AA etc...I have to be interested in the theme/what it's about in order for me to see it. Considering I have no intrest in the film, it would take some kind of miracle for me to see a show of it.
Now SLoP on the other hand, while the film was basic popcorn filler, I can see it working fine as a trackless darkride. An' I would be more then happy to experience that attraction.
So a trackless darkride which I'd ride, or a show of any sort which I have no intrest in seeing? This is not a win-win selection here.
