I've made this sauce many times, and I like it for what it is. I love to doctor things, too, but sometimes a classic is a classic. That being said, I would add two observations:
-Fresh, blanched, peeled, and chopped tomatoes work well, too. Lean toward longer cooking time. Haven't needed to add water when using fresh.
-I finely mince the vegetables, particularly the carrot and celery. Otherwise, it has a "beef stew" appearance that my family finds less appealing.
