I seriously dislike the overlay, and would not be upset if they got rid of it entirely and forever. But then I've never seen the movie b/c I don't want to, I don't like the images or animation style I've seen of it.
Hubby, however, likes it.
Our first trip as adults HM was closed to put the overlay on. Our second trip I couldn't go on it because our then 2 year old freaked out in the stretching room when all of the adults apparently were scared out of their minds and screamed (they should have "fun"-screamin-FREE stretching room "rides" throughout the day) and DS and I had to take the scarier-than-anything, black-walled, went-on-forever, chicken exit.
When we went back in September, it opened on our last day there, and I finally saw it, and hated it.
In January I went there right after it re-opened, and was at last able to see it "normal" since I was a kid, and I loved it. I'm a HM purist.
So I can't tell you you will love it, b/c I am the polar opposite of loving it, and will now avoid it during the overlay!
