Critical can mean extremely important, decisive, or urgent. It can also be used to describe something that involves careful evaluation or judgment, often with a negative tone when it refers to reviewing or analyzing something. (I) "The patient was in critical condition after the accident and required immediate surgery to survive." -- Correct usage Here, "critical" refers to a life-threatening medical condition. (II) "The critical analysis of the movie left many people in awe of its cinematographic techniques." -- Incorrect usage While critical can refer to an analytical or evaluative review, it more often carries a negative or judgmental tone (pointing out flaws), rather than a neutral or positive tone. In this sentence, "critical" is incorrectly used if the tone was not meant to imply judgment or a negative review. (III) "The manager gave a critical review of the new employee's performance, praising her efforts." -- Incorrect usage The word "critical" here suggests an evaluative review, but the sentence implies that the review was positive ("praising her efforts").
