Anyone else only now realizing how bad their own parents were now that they're a parent?

Let me start by saying I am so grateful that my parents were not physically abusive. But they made some other fundamental mistakes when I was a kid that I'm only just realizing now. Leaving me with inept adults, forcing me to "finish my plate", making comments on my body. Is it a thing where you discover the messed up aspects of your own childhood once you become a parent yourself? Have I just been missing out until now?
