That's because it wasn't going to be her at all. It was a nameless worker in the early script. So no reaction as it wasn't going to be her. The actress herself asked to have her character killed in an insane way. So, it was her idea. Also, she was a complete jerk and mean to kids in the first cut but most of that was cut for time making her just a grump but not really bad in the final film making her death worse but if you kept the deleted scenes in, she was worse treating the kids.I did not like it at all. or hearing her scream. And what bothered is more is that no one cared. Not the kids she was watching or her boss. She was there for two seconds at the start, then eaten and no one gave a damn.
Also yes that death got backlash when it first was in theatres.
Inside out--the scene where they send the ad up the tube to annoy the others. I saw that in theatres and went "wait? Just send the memories up the tube!" Movie over! Ironic how it should have ended even called it out later. That scene ruins the movies plot of getting the orbs there fast and makes joy look like a dimwit for not using it. It never should have been in the movie. It solves the trouble at the start of their quest!
