middlebrow
Neither particularly intelligent and refined nor particularly uncultured or crude in style, content, or quality. I used to pride myself on my refined tastes when I was in college, but they've become positively middlebrow since I settled down as an adult. It's an inoffensive, middlebrow film aimed at middle-class parents in need of a few hours' distraction.
