In general, a work in a visual medium - a painting, a comic book or a film - supplies ALL or most of the inputs. A book supplies only some of the inputs and we, the readers, supply the rest.
Here's the thing: a good reader supplies good inputs and an average reader supplies average inputs. This is why children are described as "imaginative readers". They "live" in the story-world whereas we adults skim through it.
So even if it's a Harlequin novel, you can make it as vivid as you'd like. But that effort will be substantially more than watching even a good film adaptation of a Harlequin novel.
