The following is better

getReviewStars :: [String] -> String
 getReviewStars args = fromMaybe "" $ f args
   where
     f :: [String] -> Maybe String
     f = fmap (T.unpack . reviewStars) . (readMaybe <=< listToMaybe)

Even better

getReviewStars :: [String] -> String
 getReviewStars args = maybe "" (T.unpack . reviewStars) ((readMaybe <=< listToMaybe) args)
