Just as yours is such a typical response to someone explaining their choice in a photograph when that choice called to question and the critic disagrees with what the photographer has to say. Your critique is not universal fact.
He didn't explain anything. He just said it was intentional. I don't care about that. This doesn't make it successful. I've made lots of bad choices in my stuff, choices I made intentionally.
I don't mind people disagreeing; I don't mind dialogue, but essentially saying 'yeah, but I'm right and you're wrong' isn't dialogue, it isn't an explanation or reasoning. It's just arrogant. It's an attitude that says "I don't make bad choices/any choice I make is always good".
If you're only willing to look at what was overseen in your work, you'll get
nowhere. Those are like the little typos, with enough practice and feedback you'll get through them.
What you want to really listen to closely to is criticism of what you did intentionally, and really discuss what it was that motivated that choice and how that choice was or was not successful.
Those discussions are way more useful to me, and I never write this kind of critique off the way that the OP did here.
