Too on the nose

Take a subjective matter such as painting. If you're going for freedom, expression of movement, light, etc., rendering something in too much detail can ruin the effect, in essence, the rendering is too perfect and therefore lifeless or absent of movement or subtlety."Too on the nose" is a phrase that is used to describe something that is too obvious or straightforward. It can be used to describe a variety of different things, including a plot twist in a story that is too predictable, a joke that is too easy to understand, or a situation in which the intentions of someone are too clear.
For example, if a character in a story suddenly reveals that they were the villain all along, and there were no clues or hints leading up to this revelation, it might be described as "too on the nose." Similarly, if a joke relies on a punchline that is too obvious or easy to predict, it might be described as "too on the nose."
In general, "too on the nose" suggests that something is lacking in subtlety or nuance, and is therefore not as interesting or effective as it could be.
