Reviewers are responsible for not just pointing out issues, but also providing (at a minimum) some form of direction, or (more ideally) one or more explicit suggestions as to how to resolve those issues.

This is an essential component of a productive code review culture.

Yeah, a good review must explain why, and should ideally explain how it should be instead if it needs explaining.

* This code should be changed looks bad - not a good comment

* This code should be chabged because ten nested ternaries gets hard to read - better

* This code is hard to read because there are ten nested ternaries. Can we replace it with a helper method that returns one value using if blocks? - best, in terms of actionability
