Expressing that something is mediocre, below average, or not as good as expected. Japanese uses various negative constructions with あまり, そんなに, or specific adjectives like 下手.

The most common and neutral way to say 'not very good'. あまり + negative adjective softens the negation.
This movie wasn't very good.
His Japanese isn't very good.
Similar to あまり, but implies 'not that good' in response to an expectation. Slightly more conversational.

Colloquial adverb meaning 'not quite' or 'leaves something to be desired'. Often used on its own or with だ/だった.

To say someone is not very skilled or proficient at an activity.
Standard way to say 'not very good at' using 上手 (skillful). あまり + negative.

Direct adjective meaning 'unskillful' or 'poor at'. Stronger than あまり上手じゃない. Can be softened with ちょっと.
Means 'weak point' or 'not one's strong suit'. Implies a lack of confidence or dislike, not just lack of skill.
To say that one's physical condition or feeling is not very good.
Used for physical condition or the state of a machine. 調子 means 'condition'.

Do not directly translate 'not very good' as とても良くない, which means 'not extremely good' and sounds unnatural. Use あまり良くない instead.
