On the one hand, you're right (and I appreciate the response rather than the downvote!).
On the other hand...
I'm an amateur writer (I admit, this is far from a journalist). Sometimes I'm just wrong, or I write something that ends up coming across differently than I expected. I always welcome feedback, even if I disagree with it, or I think it might be driven by some bias. It doesn't mean that I'm going to change it. But without such feedback, I'm not sure I'd ever get better. I guess I'm worried that in your world, journalist would be living in an ivory tower.
This constantly happens. People submit editorials with their opinion about what others wrote. People write-in to journalist all the time - to agree or disagree.
A movie review isn't an objective piece of pure journalism. It's much more of a subjective editorial, and as such, should be open to far more feedback.
