Sorry, but she lost me in the first paragraph.
After all, does a French chef need to master the art of the tamale?
If you can't even come up with a suitable metaphor, I cannot muster the interest to read your thoughts. A French chef is an artist of a particular kind of food. A tamale is an ingredient in another kind of food. What you're saying is you're a film critic who only likes a certain kind of film. Ergo, you're not a film critic. You're someone who wants to review drama/foreign/indie, what have you.
