At the risk of sounding tautological I will say that good comments are good and bad comments are bad. Code of which it is unclear why it is the way it is should be commented. Any sort of rule that comments should be written in certain places, e.g., 'comment every public method' train people to write useless comments. In a way writing a comment is an admission of loss. I have failed to write code that was clear enough, so now I have to add a comment. Most code is quite straight forward. As a rule of thumb if you have some code that is neither highly complex nor very straightforward maybe a comment is needed once every one hundred or two hundred lines.
