I think it's likely to indicate low quality. Comments are for where the code wasn't clear enough.
Comments when done correctly are vital.
Correctly done comments are a one in a million thing. In my experience, they are utterly surpassed by "i = i + 1; // increment i" style comments. (Seriously, I'm working on code written by someone who teaches programming and he writes this type of comment.)
The code to do this is simple, but not concise, leaving a comment so I can scan the function and skip 5-10 lines doing something trivial is nice.
