For an old mine brilliant, is it bad if the GIA cert reads "crown angles greater than 40 degrees"? I'm not sure how this affects the look/quality of the stone.

No on the contrary, you can't judge optics by a grading report but I would be more suspect if it didn't say that. Steep crown angles are representative of the vintage style and combined with the right pavilion lead to excellent light return.
