It's one thing to be walking along the street and happen to come across some musicians, singers, performers, or characters and pause for a few minutes to enjoy them--or even to even not pause but still enjoy them as you walk by. But this is something different.
It's a sit down show that's, I don't know, let's imagine 15-20 minutes long, at a huge outdoor amphitheater. Very few people are going to want sit out in the hot Florida sun for the duration of the show, especially if it's as cheap, and tacky as it looks in the promotional video. My prediction is lots of empty seats and lots of people walking away during the performance.
No, not everything needs to be a giant blockbuster spectacle, but even small things can impress with skill with artistry. At Disney even small things should be good. This show, however, looks sad and insipid and I don't think it's going to impress many people--not even little kids. We shall see.
