Unremarkable, misguided hero faded, I’m told (6-2-3-4)

I believe the answer is:
middle-of-the-road
'unremarkable' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'misguided hero faded i'm told' is the wordplay.
'misguided' is an anagram indicator (letters guided into the wrong places).
'hero'+'faded'+'im'+'told'='herofadedimtold'
'herofadedimtold' anagrammed gives 'MIDDLE-OF-THE-ROAD'.
Can you help me to learn more?
(Other definitions for middle-of-the-road that I've seen before include "Unexciting" , "Average" , "Avoiding extremes; moderate" , "place for dangerous drivers?" , "Safe" .)
