Pizza and movie night

I have been trying, really trying, to get my kids interested in movie night.  They will sit for endless episodes of shows like Dora, but for reasons I don't quite understand, have a very hard time sitting through a children's movie. They seem to think that movies are scary (all of them) and spend much of the time cowering behind the couch waiting for the (nonexistent) scary parts to be over.  I tried again last week when Josh was out of town with Cinderella and pizza and met with mixed results.  They mostly liked the movie but found Lucifer the cat to be way scary.  I don't get it but I'll keep trying.
