I tend to have no ability to notice directing or writing similarities between movies or television shows. I have friends who can see one episode of a show and realize immediately that it must have been the same writer as another episode because of how they're written. Similarly, a colleague in grad school was obsessed with seeing movies by certain directors because he really liked their styles. While I have no doubt that I probably have my own writing and (theatrical) directing style, I'm oblivious to those of others.
HOWEVER, I am a big fan of Studio 60 on the Sunset Strip, and an above-average fan of The Newsroom and Sports Night, which are three of Aaron Sorkin's four television dramas. (The fourth being West Wing, which I don't enjoy.) I don't know that I would have put certain trends together stylistically, but once I watch this parody, I can pick out mechanics that I've seen before in this series.
Did you notice these things as Sorkinisms before, or are you putting them together now like I am?
