Would having an expressive face be a good thing or bad?

I was told that I’m good at making facial expressions, even under a mask. But is that a good thing? Because I have a RBF and people assume what I think of them or am feeling by my face all the time even though I don’t mean to convey my thoughts and emotions through my face especially when sad or angry.
