"He sort of gets comic moments. Not a lot of directors do"

This quote by Kevin McDonald is referring to the director's ability to capture comedic moments in a movie. McDonald is indicating that few directors have the capability to catch these moments in a way that is both humorous and reliable. He is suggesting that the director he is referring to has the ability to do this, but not to the very same level as other directors. This could be due to the director's absence of experience or lack of understanding of comical timing. It could also be because of the director's lack of creativity or lack of understanding of the comical category. Whatever the reason, McDonald is recommending that this director is not as proficient at recording comedic minutes as other directors.
