I'm not a native English speaker, but I think there was definitely an idiom that describes a book, a movie or a screenplay that has a poor story line, shallow characters, too much heroic pathos etc.
I think it was something like "cranberry sauce"... Or "cranberry jam" maybe. Definitely something with berries (I think).
"Golden Raspberry Awards" mentioned in the comments does ring a bell, thanks. But is there an established idiom to describe it? Something close to "pops", "bubblegum culture", "kitsch"... We do call it "cranberry" where I live in the EU, that's why I'm asking.
