My DD7 who can be a scaredy-cat was not bothered by them. I was surprised. When I mentioned I didn't like them, she brought up the Tom and Jerry and the other cat one. I had to admit those were fine, but the rest of the clips I was not thrilled with. Just not pleasant dinner entertainment to me, but I guess if it was something else, it couldn't be "Sci-Fi".
So I could see some kids having a problem with them, but I guess you won't know about yours till you try! My kids thought it was cool to sit in the dark in the cars, but that was not enough for me to override the unpleasant films and bleh food. We won't be going back.
