My DD5, who is as tough as nails and who loves Haunted Mansion and who also rode Test Track for the first time last week - HATES that show!!! We took her last November and she was on the floor covering her eyes and SCREAMING along with all the other little kids in the audience.
If you sit in the back you see more of the effects. Near the end it is dark, the lights flash and the grasshoppers come down from the ceiling - very intense!!!
I think it's a fun show, but if you only mention it to DD she says over and over that she will NOT go on it ever again.
That said, some kids will go to the show and have no problem at all.
When she was younger she thought the bugs had actually sprayed acid on her.
