Google snippet when searching for "code smell martin fowler":

"According to Martin Fowler, code smells are not problematic on their own. They are warning signals that there might be a real problem in the code. For example, long functions are considered a code smell, but not all long functions are necessarily bad or poorly designed. Fowler suggests that junior members of a development team identify code smells and review them together with senior members, who can evaluate if there is really a deeper problem in the code."

And the first google result, which is Martin Fowler's own website:

"The second is that smells don't always indicate a problem. Some long methods are just fine. You have to look deeper to see if there is an underlying problem there - smells aren't inherently bad on their own - they are often an indicator of a problem rather than the problem themselves."
